I purchased Alpine component speakers for the front and Alpine 2-ways for the rear. After inspecting the original stereo components, wiring, etc... I cannot find where the crossovers are. I assume that I need to replace them as the Alpine component set came with them. Any Ideas? Also, any Ideas on locating a wiring diagram for the system?
Any input would be great!
I was the guy who had the transmission problem a couple of weeks ago (wouldn't go into gear). Anyway, after the Dodge dealer's service guys didn't find anything and I've driven the truck a week, the SAME thing happened again - I couldn't shift into any gear. This time, armed with your (Dusty's) info and some Internet snooping, I held the shifter (clutch depressed) in the REVERSE position and turned off the ignition key. The shifter handle fell right into the reverse position and when I started the truck back up, it's been shifting just fine ever since. I called the service manager, told him what I encountered, and I hear him brief the shop foremen about it. They seem perplexed by the whole idea that it might be a bad clutch slave cylinder. Are these guys "thick" and just not getting it? I'm fairly mechanically-inclined and my question is: Could I purchase a slave cylinder and do the work my self or should I buy the part and take it somewhere else? These guys evidently have not clue.
Feedback greatly appreciated,
Jim
After a series of numerous MIL illuminations (with P0121, P0441, P0440) and numerous visits to the dealer that revealed no hard DTC errors, the dealer has discovered a failed pump unit (HVCC?or HVOV? or something sounding like that) not clearing the various DTC codes properly. After the last visit, the MIL light has come on again with a P0440 and the gas cap is on tight. A new pump is now on backorder. :sick:
Anyone encountered this situation? Is this pump a component of the EEC? How does it work? :confuse:
Thanks.

This is a simple air pump that can often be heard when you first turn the key to "run" before starting the engine. It makes a "vibrating" sound. This air-pump simply attempts to build a slight pressure in the air above the fuel in the gastank.
Then, it seals the system to make sure that the pressure can be maintained.
If it cannot build up any pressure (gas cap loose, broken hose...etc) that will flag a code.
Obviously, if the pump is not even working, the computer could flag all kind sof false fails. (the compuer ASSUMES that the pump is working)
My factory service manual has an entire section on how this pump is used and what "tests" are performed to check for leaks in the system.
I guess that explains why all the erroneous codes keeps getting re-flagged after resetting. Although the MIL light keeps coming back ON, their diagnostics did not find any hard DTC codes set using their shop scan tool. Apparently, the last DTC code previously flagged is not being erased in this situation, thus re-activating the MIL light after the system reaches it pre-determined number of drive cycles.
Thanks for your explanations. Most helpful!
After that hose had popped off 2 times, I put a hose clamp on it... problem solved forever.
"The Malfunction Indicator Lamp (MIL) gives an indication to the vehicle operator when the Powertrain Control Module (PCM) has recorded a Diagnostic Trouble Code (DTC) for an On-Board Diagnostics II (OBDII) emissions-related circuit or component malfunction."
Illumination of the MIL can be a momentary flash or a constant illumination depending on the type of fault being detected by the PCM. For some types of faults the PCM will transmit a reset signal that switches the MIL off after 40 engine warm-up cycles or if the problem clears. Others will remain illuminated until the fault is repaired and/or the PCM is manually reset.
As to codes not being stored, this is contradictory to the design of the system. However, it is not uncommon. It's possible that at the time the OBDII scan tool was connected occurred after 40 complete warm-up cycles. Another explanation is that certain codes do not remain in memory if they clear on their own, although that doesn't make any sense to me.
A third possibility is on older vehicles with 3-6 year old batteries. Some Dak owners are aware of the strange relationship between the battery and poor or rough idle, random stalling, irratic transmission actions, and otherwise unexplainable quirks. My suspicion is that with certain close-to-failure battery scenarios the battery intermittently loses power for an extremely short duration causing the PCM to reset. This could cause an erasure of codes stored in memory. I know of two Dakotas, a 2000 and 2001 model, that kept losing stored codes until the batteries were replaced.
Hopes this helps.
Bests,
Dusty
Also, what years will work in my truck?
Thanks,

Just read your message of 06 Jan 2005 where you state that you just resolved a PO456 code. I just got that code (PO456) about 4 or 5 days ago and it just cleared by itself. How did you fix your code may I ask? Thanks. rewebber.
thanks for the info; looks like we both have 2003s. The service manual information makes a lot of sense. In my case, the MIL has remained lit and has definitely exceeded 40 complete drive cycles, yet no hard DTC codes are found in memory. This morning, when I cycled the ignition key for checks, 2 back-to-back codes (P0441,P0440) popped up.
The faulty pump unit is being replaced by the dealer under warranty later this week and I'll post any relevant info as appropriate.
Thanks again. Most helpful.

Another way is to look on the transmission case. There should be the type cast into the case in large block letters.
My guess would be that you have a "RE" series, which means an electronic version. The "RE" stands for "Rear-wheel drive, Electronic." The "RH" stood for "Rear-wheel drive, Hydraulic."

2001 QC 4.7 Auto 4x4 operating normally until today.
Got in this morning with normal interior overhead illumination and key chime, then turn the key and <1 sec flash of system startup, then no power.
The electrical systems resets itself "somewhat". After several minutes, power is again available for interior light, key chime and door locks with engine off.
Went the key is turn same situation or if the headlight switch is turned on without turning key first. Then power cut out, time out period, then limited power.
I'm checking fuses and relays but not an expert. I do have the 01 service manual (orange book, although that year it was green!)
Thanks.
Have you checked the battery terminals and charged the battery?
(PS) Most auto-parts stores will test your battery for you.
That's one conclusion I came to as well. One of the first things I did check it with a simple meter, but only volts, not amps.
Also, cleaned battery terminals and cable connectors. Did not start (same symptoms) with jumper cables.
As you advise, going to stick to checking basics a while longer before calling the dealer.

Even if it took a charge doesn't look like it's ever going to be able to get back to its old self again.
After 4 years of absolutely no electrical problems, I think it's time for new battery. I realize it is possible there's a problem in the charging system or other electrical circut fault that can drain the battery, but I think this one is telling me it's done.
Like other comments, plowing with a truck is tough on the platform. Even 1/2 ton versions get beat up pretty bad. Signs of a plow frame on a truck usually kill resale value.
The Dakota is a tough and durable mid-size truck platform. Occasionally I will see a flat-bed Dakota even. But for plowing I agree with Bpeebles. I'm sure it would serve you fairly well in that duty, but it wouldn't be my first choice to plow with.

I am having a problem with my 95 Dodge Dakota 3.9L. Before
I go ahead and put a new computer in, I want to see if anyone else has
experienced this problem and knows what may be causing it. At random,
the A/C will turn on and the OverDrive will turn off at the same time.
Clicking the OD button has no effect on it and all of the fan/air
conditioning controls are turned off completly yet the A/C is still
running strong. My guess is it's one of two things, either the computer
is going haywire or there is a loose ground somewhere. I haven't had a
chance to really look it over, but has anyone else had this happen? I
did check the fuses and relays and all is fine there.
Thanks,
Josh
Has anyone else noticed a problem like this on their Dakotas?
For increased piece of mind, have your dealer inspect it and have it on record.
Best regards,
Dusty
Dealer says "that's within specs"
I'm running full synthetics in the lowest recommended viscosities for all lubricants.
Any other possiblilites?
I noticed that when on highway with cruise control on, it feels like it wants to change into passing gear.
My question is this, the cruise control, or worst the transmission. Anyone else had this problem.
Got my break pads and rutters *sp replaced, the front ones. Recently, everything was working fine! Then next day I get in my truck to go somewhere and all the ABS and BREAK lights come on, shortly after the CHECK ENGINE light comes on.
I notice shortly after while being mezmerized by the lights that my spedometer is no longer working either... I then look at the other lights oil, gas, water, etc..they are working fine. My Odometer,..*sp has stopped at 102,901 and is no longer taking count.
I take it back to the break pad people and tell them they better double check thier work cause now I have alot of lights on mostly dealing with my breaks and I don't know wtf is going on.
The man 2 hours later comes back to me and pretty much tells me he has no idea whats going on, and that the computer is giving out two readings about two diff problems. One being some #72...I forget what it said...and another he siad had to do with a HUC... or something like that. CAD? or CAB? Two problems relating to those. I don't know. But he insist nothing is his fault. And then further tells me that he can't find the problem because he doesn't have dodge certified software to understand the computer and that he only recieves a generic read out, because dodge doesn't share thier software or something?
He says that two possible sensors are not working, one being the one with the spedmeter, and the other being in the back dealing with the back breaks which they didn't even replace, so the fact that it is all not working...is just coincidance.
Now I have to take it to another place course cause this place I had the breaks replaced at is a "Hibdons" which as Im sure most of u know does mostly tires.
I take it to another place and they tell me its going to take 78 dollars for them to use thier generic computer on the truck in hopes they can find out if it really is those two sensors or what not. and then after the 78 dollars they will see if they can fix it.
Now Im sure you are all just titalated by my story, but your wondering..okie whats the question again?
I guess its a couple questions.
1. One being , wtf , dodge software!? Where can I get ahold of some of this! and who uses it!? If I go to the dealer about this Im going to get raped! And no thanks.
My mother has some theory about the manufactiors installing sensors that auto distruct at 100,000ish miles or so , so you HAVE to take it into the dealer. I donno she's crazy paranoid imo.
My other friend says that if they didn't put in the break lines or something correct they could have pushed back into the truck the old fluid which might have caused the break light and abs light to go off...because it would have fed into the back sensor by the breaks, and that one might then read to the spedometer sensor then breaking it, oh yea and my anti lock breaks are no longer functioning.
Tho the break guy tells me that has nothing to do with what he did either. He also mentioned to me in there that the problem with my truck was right on the front of it, refering to the dodge symbol on the front of my truck...what a smuck...Tho IM thinking okie I take my truck in for break pads and a day after I get it back I no longer have anti lock breaks?! Sounds fishy to me, but Im okie with just calling it a coincidance...but personally I want ur opinion...2. what do u think might have happened?
...anyone got any ideas?

A little more information would be helpful. You don't say what transmission, body style, 4x4, or how many miles. Nor did you indicate if you used the cruise control on highway trips or how hilly an area your in. There could be some engine tune issues affecting your trucks fuel consumption, like a dirty air filter, worn spark plugs, or a clogged PCV valve.
The one area that will have the most impact on an otherwise mechanically sound and correctly running 4.7 is the driver's style. If you're the impatient type of driver your mileage is going to be lower. Mountainous areas or lots of traffic stops and start ups will hurt, too.
My occasional trip down I-90 to the Pennsylvania border from Rochester, New York, always yields me over 20 MPG and that's with a 800 pounds of ATV and other gear (4.7 automatic, 3:55 rear axle, Club Cab, 4x2) and at a steady 65 MPH.

The "Dodge software" comment is bankrupt. First, all manufacturers now use a universal diagnostic code system called OBD2. If they have an OBD2 read-out tool and the correct program software there is nothing special about a Dodge over a Chevy or anything else, except that some codes are unique to various manufacturers.
The illumination of the ABS and brake lamps indicate a specific malfunction in your brake system, the loss of the speedometer and odometer is something else. It generally means a loss of PCI bus information. There may be a relationship.
Check all of the fuses in the junction block that is located on the drivers side of the instrument panel. Be especially mindful of the IOD fuse. It should be number 10 on the block. Some are labeled "engine relay," but this fuse can open and cause weird symptoms. If you have a fuse that's opened, inspect the vehicle for pinched or damaged wires in the area that your so-called "mechanic" was logically working.
Your ABS isn't working probably because the ABS or PCM computers have detected a fault. Anyone with an OBD2 diagnostic tool can pull a code off of the PCM. You can also see the codes that are stored by cycling the ignition switch on-off-on-off-on (not to the "start" position). Wait a second or two and observe the odometer read out for "P" codes.

Dusty
Can I go 5 days without it being checked out by a mechanic? I hate to do that.. but I really can't afford the time without my truck... and going to the dealership is not an option.
The Malfunction Indicator Lamp (MIL) illuminates when the Powertrain Control Module (PCM) has recorded a fault related to an emissions system problem that is twenty seconds or more in duration or there was a loss of bus communications (PCI). The MILs illumination pattern is determined by the type of fault. Some problems will cause a MIL to flash, others remain solid. Some MIL causes must register a repeat pattern over a number of engine restarts or "good trips."
A MIL illumination may clear by itself under certain conditions, for example, if after 40 restarts the same fault is nor registered with the PCM, or two or three "good trips" are completed without a recurring fault.
Try to obtain the diagnostic trouble code (DTC) that's causing your problem, either by performing the operator intitiated PCM test, or connecting an OBD2 or OBD3 read-out tool.

Dusty
YOU HIT THE NAIL ON THE HEAD. IT WAS THE COIL. THANK GOODNESS IT WASN'T THE FUEL PUMP LIKE THE DEALER THOUGHT AT FIRST. $700 FOR THE FUEL PUMP REPLACEMENT. BUT "ONLY" $192 FOR THE COIL, WHICH I THOUGHT WAS A LITTLE STIFF. BUT THE TRUCK SEEMS TO BE OK NOW. NO PROBLEMS. THANKS FOR THE INFO. GRANPAPPY
Anyone out there that might have some home remedies or suggestions, before i mortgage my house to have the dealership look at it?
The dealership recommended a fuel injection system flush $$.
Thanks!
Here is one air filter study:
http://www.bobistheoilguy.com/airfilter/airtest1.htm
Oftentimes, the oil from those filters migrates (gets sucked) into the intake system and causes all kinds of problems. (Like gumming up the Idle system)
The first thing you should do on your 4.7L is the CLEAN THE THROTTLEBODY.
Also pull off the Idle Air Controller (IAC) motor and clean it and the hole in the throttle body it mounts into.
After re-installing the IAC, start engine and LET IT IDLE for at least a minute. Do not touch the throttle while the computer "relearns" how to idle and automaticly re-adjusts the IAC.
