I would first check the wire that comes from the oil sending unit. I believe you have a V6 engine so it would be located near the oil filter. It should be removed and cleaned and make sure it feels tight as you plug it back in. Try this. If no luck replace the oil pressure sender it was attached to; that should take care of it. ...1930fcoupe My 2001 Trooper's oil gauge started acting up and I thought it may be the sensor. The next thing I know the lower end is rattling and the oil light is coming on when it was at idle speed. (93000 mile) I took it in and they say it's about to throw a rod. Rebuilt engine is $6000+. Don't mess around with the oil lights and gauges. I've heard stories of these engines using alot of oil.
If all of the gauges stopped working there is probably a blown fuse in the right side of the console in the car or out under the hood in that fuse box. If all of the fuses are good then there is likely a bad gauge cluster or a wiring problem.
You may have an electrical problem. need a professional tech to look at it. I just found out that it is a gauge cluster problem. This is not the first time I heard this as I did call the dealership and explained to the mechanic what was happening, he said and the same thing. It is not uncommon for this problem in trailblazers. If the gauges are not working, then your battery is not getting charged up.
Definitely take apart the gauges, check and make sure all cables are intact.
there was a recall for that .call dealr to see if you qualify
I had the same problem...it was the "computer". I had to hit the dash for about a year, then it just stopped working. It was around 800.00 to fix. You need to do at a Chrysler dealer as they have to input the codes that your local mechanic will not have.
buy a new car
They might be broken, check with a mechanic, its illegal to drive when they are broken.
gauge wiring may not be hooked up if they have never worked or if they have and just stopped working maybe a fuse i would check all your fuses
I have a 1991 E-150 hightop with 110k miles on it. both the gauges stopped working I had to replace both sending units and that worked
A wire going to the battery broke off, when it was reconnected the gauges and lights on the gauges start working again, however the speedometer and the tachometer did not operate.
Check the gauges fuse ... may be a short, bad wire or a bad ground. Doesn't happen open but your cluster may be bad as well. NELSON
Check the fuse. It says [guages]
