Isuzu Trooper



  • I have a 94 Trooper S series w Power windows. I have lost power to the main switch and had to bypass it to make them work. The fuse is good and has power.Is there a additional relay or switch that can cause the power fail? Tried wire diagrams for the car but nothing on Power windows. I think it might be tied to the starter switch or relay. Help

    Anyone experienced a failure of the muffler on your Trooper? My 01' started making an unusual noise some time ago so I had the mechanic check it out. He said the baffles inside the muffler had come loose, causing the noise. I priced a muffler from St. Charles ISUZU.......$509 !! I think I'll go with a generic. I've replaced a Trooper muffler in the past, but the quiet sound just wasn't there afterward, it was a throaty sound. Anybody got a brother-in-law in the muffler buz?

    I have been told by, my trusty mechanic, that there is a problem in the exhaust where some metal parts come loose inside and rattle. They said repair would be temporary, since the new parts (it is fair to assume they were talking about genuine Isuzu parts) would fail the same way.
    So, If you find a suitable alternative that does not return to the rattle, please post about it. I will then fix mine.
    Meanwhile, the rattle is only during certain types of acceleration and then only for several seconds, not really all that bothersome to me.

    I just discovered that one of my rear brake lights is not working, I'm assuming its a burnt bulb. Is it relatively straightforward to replace the bulb? I'm assuming I have to loosen the 2 screws & the whole light assy comes off, and then simply replacing the bulb. Any input would be appreciated, its a 2001 Trooper. Another problem I'm having is with the tailgate power lock, it always opens with the other power locks but doesn't always close. Has anybody else had the same problem? Don't really know how to start troubleshooting this one. Thanks.

    Don't know about the 2001 Trooper, but on my 1999 there are 2 screws on the outside AND 1 screw and 2 tabs on the inside that you can access by opening the rear doors. Once you have the unit loose, just turn the bulb holder counterclockwise and remove. Should take about 5 minutes. Sorry, but I can't help with the tailgate lock.
  • kobokokoboko Posts: 34
    Thanks, replaced the bulb yesterday, was pretty straightforward as you mentioned. Only thing I noticed was that the rubber seal was disintegrating with age, might have to replace it if another bulb goes out in future. Now I have to try to figure out the liftgate power lock problem...

    MADDY :confuse:
  • I am new to this forum, and look forward to responses. My 1996 "Trusty" has 158,000 miles, and has moved with me to the Virgin Islands. There are many shade tree mechanics and each has a different view. The "clicking" sounds come and go, and one person suggested finding out the "lifter" type for this model to determine how to help. Does anyone have a suggestion? Also may need some transmission help soon. Would a replacement transmission be better than a "kit"? Thanks!
  • bsmart1bsmart1 Posts: 377
    Your 96' Trooper has the 3.2L V6 which is known for the 'clicking' or valve 'ticking' sound. While it is annoying, its very common, and not a threat to engine life. Many things have been tried to remedy it, but few have had lasting results. I wouldn't waste much time worrying about it unless it gets very loud, which might the sign of impending engine failure!!

    The transmission on the other hand is a different issue. A replacement Automatic will cost about $5K and repair quotes typically run about $2K. I hope your's isn't in serious trouble.

    Has anyone on this board swapped the ECU or the chip from a 2000 - 2002 model Trooper into a 1998 - 1999 Trooper? I have an 01' and a 99' both of which run just fine, but the 01' will run circles around the 99'. I believe it has to do with the electronics on the 01' and the programming of the ECU, or chip. If a chip replacement would work, i'd do it in a heartbeat!!
  • I have a 93 Trooper with the same ticking sound. (Pushing close to 190,000 mile on the baby).

    Actually there are two sounds I get - one is the engine itself which has been there pretty well for some time. The other seems to be associated with the timing chain. I've come to notice that the timing chain tends to rattle more when the oil is low (pressure still OK though).
  • I am having the EXACT SAME ISSUES with my 1998 trooper right down to the switching back and forth from the fresh and recirculated air will sometimes bring it back to life. I already changed the voltage regulator and it seemed to help for about 3 months. The blower motor seems OK when removed and plugged into 12 VDC.
    Were you able to fix your problem? If so could you detail how you fixed it for us?
    Thanks a lot.
  • atfdmike:

    I determined that the problem with my heater blower was the resistor controller (don't know what this piece is called). By examining it, I figured out which were the "bypass the resistors connectors" were in the plug, and I jumpered it with a piece of solid 14 guage wire. When I turn the fan switch to high, it blows like stink.

    The resistor controller unit is held into the air duct with two screws, just "downwind" of the fan, right behind the glovebox. Take out the glovebox (four screws) and you on it.

    Now, to find an Isuzu dealer that actually has the part...

    Thanks for your help with the wiring diagrams and the concepts.
  • can any body tell me what xs means,i think it has something to do with the transmission.does anybody elses trooper have two buttons by the automatic shifter that says power and winter drive. thanx
  • atfdmikeatfdmike Posts: 414
    Hi, Sounds like you worked it out. Good luck finding part, but maybe you can adapt a different model if you can't find the exact match.
  • atfdmikeatfdmike Posts: 414
    The Trooper you have has the options to increase traction on slippery surface by starting and staying in 3rd gear. That is your winter drive. Usually the instructions were on the driver's visor. I believe you can just hit the button while driving to turn it off and the next time you stop, it should be back to normal. The Power switch changes the shift points of the trans so that it will keep the torque curve in the optimum band. I have only known it to be used for towing a load.
    I am not sure what the "xs" you refer to is about. Hope this helps.
  • I'v been burning oil @ a quart every 1000 miles. Is there reason to be concerned? Thanks.
  • Can you provide some instructions on cleaning the EGR valve? I'm not that familiar with it. Also how do you replace the PCV valve? Thanks for any assistance. BTW...I have an '00 Trooper LS, 2X4.
  • I've been tracking the closing prices on EBAY for Troopers and using a very simple linear regression (straight line) of the data I've taken (n=63), with a relationship of miles to price, I'd say a fair price is $5,390. This does not take into relationship age, condition, appointments, etc. It simply compares miles to closing price on EBAY (for those auctions that met or exceeded the reserve price). The equation for those interested is y= -0.0161+6975.

    cool equation,
    Now, automate your algorithm and create a web page, with ads for all sorts of stuff to buy.
    Next, offer the technology as a service for market research

    Don't you need one or more independent variables on the right side? :)

  • The part wasn't bad at all... $42 from the dealer.

    Thanks again.
  • I had a trusted mechanic tell me that that codes say that my MAF is bad at 80K (the CEL was on). The OEM MAFs are about $500.

    I found an *aftermarket* MAF for $155... any chance it will actually work?

    Anyone else interested, send me an e-mail and I'll send you the link.
  • There's an FAQ here on cleaning the EGR port/tube:

    If that link doesn't come through (CarSpace might not like it), e-mail me.
  • I have a 1995 Trooper 4 x 4 that I have had for a little over a year. I just noticed, first by smell, that the drivers side floor board is very wet. Looks like it soaked from the floor board up instead of floor mat down. Anyone have any ideas? Could it be something like the A/C ?

  • Could be a leaky windshield seal, have you changed the windshield lately?
    I would clean out the vents below the wipers on the hood and make sure nothing is blocking the areas around under the hood near the firewall.
    I enjoyed a 1995 Trooper for 140K+ miles before it was rear ended so hard the air bags went off and that $6000 air bag repair totaled it.
  • The A/C coil is right there, behind the glove box. The fan motor is to the right(turn it on and you'll hear it) the A/C coil is housed closer to the transmission hump. It's pretty easy to get the glove box off (two screws at the bottom hold the hinges to the dashboard frame) so you can get a better look. There is an line for draining the condensation out through the firewall, and, if it's plugged, you could get a leak like that.
  • look at the section for the EGR valve...should be links to instructions and pictures here. Also, look for the PCV valve section. There is a good diagram there that shows the location (driver side of engine). A new PCV valve was maybe $3 at AutoZone if I remember correctly, so I just replaced mine even though the old one looked and sounded okay.
  • I am looking to buy a 2002 Trooper. I am trying to find out if there major problems with this vehicle. From reading all the reviews the only thing I seem to run across is possible excessive oil usage. Any other possible problems? Like transmissions? Thanks!
  • I like to keep things simple so less stuff to break, I occasionally drive my Trooper very hard, and I like the tight coupling of a clutch vs torque I have always bought manual transmission Troopers. More fun less to break. However, the later year Troopers with automatic have TOD which manages 4wd so that you can drive 4wd on patchy ice roads, a feature which I think is really nice.
    I have had 1984 Trooper 201K miles, 1995 Trooper 140K miles, then rear ended, totaled even though it was still drive able. Now I have a 2001, very nice one previous owner who took great care. I have no troubles with it except that I should keep it cleaner than I do.
