I checked the wiring diagram for the amp...Pin A8 is a "radio on signal". Does anyone know what the value of the signal should be? And how to bypass it?
I would like to reuse one of these Modules for a project on another vehicle but have come up short on the main 16 pin connector and exactly which terminals are connected to ground via a switched input ( eg. Door Switches ) and which are switched via 12V +
Any info would be really appreciated especially a description of where the other connections head off to other than the main 12+ supply and the device ground connection.

I have a 1995 bonneville ssei. My signal lights want work, My husband has changed the fuse and every time the fuse is blown. I work nights so it's kinda hard to do hand signals in the dark and I don't think the other drivers pay attention to those any more. Can someone give me some feed back on what could be causing my fuses to blow.
Thank you

It's annoying at worst.
What is the problem???
Thanks!
Have had two occurrences of this both times I partially pulled the key from the ignition and got out of the car. When I returned the drivers door was locked - other doors not.
Any suggestions? Please do not suggest I remove the keys from the ignition, I want to solve the problem and leave the windows down just in case.
Contacts inside the dash where different components have electrical contacts like circuit boards in a computer have corroded and are making intermittent contact with vibration from the brake pedal. Try hitting your shoe on things in the area of the brake pedal without using the pedal.
The contacts in the ground buss at the corner of the A pillar and the floor. It's under the plastic door sill where you lift your foot in and out. Moisture in some climates can corrode the contact for the grounds which all press onto one large multicontact.
Bad connections at battery cables where two positive cables overlay each other. The corrosion builds between the two contacts. Turn off AC with car running before removing these cables.
Could be a weak battery.
Could be a weak alternator or contacts at the alternator.

You don't mention how many miles. Or whether the fuel filter has been changed. So fuel could be a problem. Th fuel pump might not be making enough pressure to squirt fuel through the injectors into a mist that easily fires. That requires good testing. The replacing of the fuel pump requires dropping the tank and is tricky and dangerous because of explosion/fire danger.
The injectors might not be firing. You can hear them or feel the click when they open while cranking if you tought them. You can take a 194 bulb like the little bulbs used on side markers and taillights that have the two wire leads and put the leads into a connector for the fuel injector and see the bulb flash as the injector is fired.
You can check for ignition spark by taking a spare spark plug and connecting a spark wire to it while it lies on a metal part of the engine and crank. It should have a good blue spark.

anyone with same experience?
You can remove the sensor and measure its resistance at various temperatures. I assume there's a table of proper resistances for various temperatures. It may be in the factory service manual. It's a relatively inexpensive part so depending on how much trouble you're willing to go through it might be easier to replace rather than test.
The same sensor is $15.98 from rockauto.com plus shipping. I'd get AC/delco ACDELCO Part # 1571823 myself. You could check autoparts stores for a quality brand.

i will report my findings as well...
i have a 98 SE, and one day i thought i blew my starter, so i pepboys said it was my starter, so i replaced it, and my care began running again...
later, every once and awhile, the car would not start for an hour or hours at end... it would not kick or even try to crank--just the same as when the starter was dead; it would just sit, dead. then later start up powerful like nothing had ever been wrong...
now, it has basically stopped working... and i think that it was never my starter to begin with...
when i turn the key, i have on "check gages" light and the "engine" light is on...
i believe the pressure and everything else is fine... and i plan to get an engine diagnostic as soon as it finally starts back up for me to get it to the car service...
if anyone has any suggestions, please contact me asap.
Then you're down to diagnosing. Checking for power at the starter itself. Then checking for power on the relay terminal on the solenoid when someone turns the key.
Then you're down to using a cable to supply direct battery positive power to the starter terminal to be sure the car's cable isn't bad. If the starter doesn't work with a direct jump, then you know it's the starter.
Using a direct cable from battery positive to the starter positive is dangerous because you must not touch the cable to anything a part of the car or you've got a direct short which will cause fire and sparks. But it's the ultimate test.
BTW has your car been dripping oil from the oil pan where you park it? When I replaced the starter on my 98, the AC Delco rebuild shop asked if it was dripping oil. He said the oil gets in the solenoid and keeps it from making contact.

Check the other ends of the connectors and the ground for the negatives. I suggest retightening them.
There are ground busses under the door sill plastic and carpet near the A-pillar. Driver's side and passenger side.
These are wrapped up in tape but still may corrode due to moisture from shoes dragging in snow and rain or open windows for some people.
Instrument panel connections behind the instruments also may slightly corrode and not make good contact. For certain problems reseating them helps.
There's no one cure without looking at the factory service manual to follow the wiring to see what shares what connector among your various problems. So I suggest troubleshooting the above suggestions.
Be sure to turn off your AC with the key ON so it parks its parts before disconnecting anything.
The only other problem area is a worn ignition switch and the contacts inside don't make good contact on certain connections out of more than one it makes when in ON or RUN. This is the switch, not the lock cylinder at the top. The lock moves a rod that operates the switch which is down on top of the steering column to make it hard to mess with in a theft attempt. Some have reported fixing problems by replacing that but typically it's a shutoff while running which restarts easily. That doesn't sound like what you're getting.

But with the hot days coming, the car is black with leather seats, no air to circulate gets really hot,,,,,
Can any one help,,, we checked the fuses,,,,,
The windows are controlled by various modules that talk to each other over the network. Do your door locks work? There's a main module in the driver's door that communicates with the other door modules. Some people find a poor connection in a braid of several wires running under the carpet under the middle of the driver's seat area. There's a connection which may corrode.
There also are several different fuses involved including under the rear seat and under the hood. The radio going off is part of the retained power and someone elsewhere just went through a diagnosis with it. I do not know if it's a part of your problem. I have not diagnosed one of these, but have read several people having done so.
Your rear window is the regulator which has a slide that moves up and down via a metal cable to move the glass. The metal cable terminates in a plastic part. The supplier gave them several which are defective and break that went into 2000-2002s the way it sounds. People take out their regulator and send them to places on Ebay or other sources which repair and return or do an exchange. I do not recommend Ebay, but sometimes they have what is needed.
If you set up your carspace email on your carspace page in the upper corner of this page which say's "my carspace" then send me an email at my carspace account which is my username in the title for this post with an at sign and carspace dot com. I'll try to help you find info.

I am a longtime lurker to this great forum and I need your help.
I just put a 2001 3.8 SC from A Grand Prix GTP in my 02 Bonneville.
The motor is in and all that is left is the electrical and the front shaft connections.
I have a few questions and need some help if possible!
1. We are thinking we need to use the computer for the GTP motor.
2. The wiring harness( where it plugs into the fuse box, and the connection in the firewall-under the master cylinder is different.) The 02 takes a rectangular plug, and the one on the new motor is round.
Anyone have any ideas on how to proceed?
Thanks
Joe
Good luck.

If you put your key in and turn it to on and the security light flashes for 3 minutes and then resets to read a new key insertion, you either have broken wires in the column where the tilt flexes, the contacts that rub the chip are dirty (alcohol on key when inserted may help), or the contacts on the key are dirty (rub with pencil eraser).
When the system doesn't read the chip right, the lights on dash all come on, but when turned to start nothing happens. You'll hear fuel pump when key is turned to on. But injectors and starter are disabled for 3 minutes after you turn the key 3 times to start with a wrong resistance reading.
You can read your resistor with a meter, and match with the 15 choices in the link I posted. Buy resistors at radio shack for a series you solder together. Or see an aftermarket alarm place; they routined bypass these with resistor sets for alarms they install.

I am wondering where to even begin to look for the problem, is it a fuse or wire or both?? I'm thinking that the water had something to do with it.
:confuse:
Check your connector under the dash for a burned contact or a contact that has unclipped and is recessed too far to make contact.
I am assuming your car is wired like an 03 leSabre. I checked the CJ2 diagram for auto temp control.
fuse #37 goes to the control, but you said the control is working other parts of the system.
On the blower motor connectors B and C are power and ground. A is a feedback to the control unit. You might use a fused jumper to see if you can apply power to the old motor and make it turn and then the new one.
Good lluck.
2014 Malibu 2LT, 2015 Cruze 2LT,
You may have a connection problem in the various battery cables and grounds. Especially grounds.
Do you hear a click when you turn the key to ON as the starter tries to work?
There also are ground busses under the door sill plastic liner and carpet on the driver's side and passenger side. Pull out the sill at the front and check for corrosion on those grounds. I do not know if one affects the starting circuit, but cars in wet climates or having leaks have developed corrosion there.
The chip in the ignition key is read by contacts in the lock cylinder. Two tiny thin wires go down the column, inside a plastic cover that looks like it's a solid wire itself, to the connector at the bottom of the column where the two inner wires split out to different connections. From there the leads go to the computer on those early years of PassKey and the resistance is read by the powertrain computer whether to allow injector pulses and to allow the relay for the starter circuit (high up on the firewall above the passenger's side where it's very hard to reach.
The two wire can be cut where they go up to the steering column and connector by a resistor series of the same resistance as the chips in the keys.
Then the computer gets the right reading for the car's key all the time. No theft resistance.
