Question about 2001 Isuzu Trooper

1 Answer

I have a 2001 Isuzu Trooper with intermittent dashboard illumination lights. The lights behind the speedometer always seem to work, but the ones behind the tachometer and temp/fuel gauge flicker are

I've checked fuses and the illumination dimmer. Pounding on the dash doesn't help. Not sure where to go from here. Oh, the former owner installed a stereo (the lights for that work). Since the lights sometimes work, I don't think that would be the problem.

    I took apart the dash and instrument cluster. No loose wires and everything looked ok. Checked the bulbs, cleaned the connectors and put it back together. Same problem. I'm guessing there's a loose ground somewhere but haven't been able to find it. Anyone have suggestions? Thanks for your help.

Often this kind of problem is caused by s faulty ground connection.

If it uses the common type of 'Christmas Tree' connector, it will have one center screw surrounded by a 'daisy' with petals bent up at an angle and plugs attached to some or all of the 'petals.'

Try tightening the center screw and pull/push back on each connector.

    Ground connections are not specific to individual functions but are return path using the body of the vehicle as a conductor so if this system is used, it will have as number of quick-disconnect female plugs pushed on to male tabs.

I have a 2001 Isuzu Trooper & the brake lights are out. Tail lights & blinkers work, the fuses & bulbs seem to be ok..what can I look for now?

There is a switch that is located above the brake pedal. It is called a brake senden switch. Make sure that it hasn't just lost contact with the brake pedal, that can happen, if it is bad, then it is a cheap fix

Isuzu trooper 2001 spark plugs

Any parts store can sell you the plugs for that vehicle. The main ones are NGK and Nipendenso. The retailer can also provide you with the proper gap.
Note; I've always found Autolite or Champion Platimun to work best, thats what we run in our company vehicles.

RE: 1997 Isuzu Trooper "Replacing the Speedometer"

I suggest you buy a repair manual if you love your Trooper and plan on keeping it!
You can buy it online by clicking on the following link @
It's pretty steep @ $120 but I couldn't find any (zero,zip) manuals for the Isuzu Trooper except this one and it's used. I'm guessing you have what will be a classic someday!
Removing the dash is a complicated process with a lot of parts, hidden screws under plastic covers, and a lot of wires you don't want to short out!
