#122 of 232 2002 Jeep Grand Cherokee 4.0 4x4 electrical problems
Jan 13, 2008 (2:12 pm)
When I turn the key sometimes the oil pressure gauge goes all the way to the right, the check engine light goes on and says its my transmission. Replaced electrical parts in the transmission. Did not fix problem. Checked alternator with check engine light on putting out low volts. Check engine light went out and by the time I got it to the shop, alternator was worker perfectly.
Sometimes ignition key won't turn to start car have to mess with it a lot to get it through the tumblers radio crackles and cuts on and off when it idles whether check engine light is on or off. can't get a straight answer from any mechanic and would like to know if the voltage regulator inside the alternator can work when the check engine light is off and then not work when the check engine light is on.
Is the voltage regulator controlled by the computer or is it independent of the computer?

Dead battery..low lights. No gauges. I am assuming a bad alternator. Before dying the gauge did not show the battery voltage...help.

I've got a 2002 grand cherokee, it have 2 problems and they seem not to related.
First is the head light problem with the head lights turned on they will most of the time cut off when i turn on the turn signal, and a few times when using the wipers. The local dealer wants $40 per hour to trouble shoot. the second is the check engine light comes on but not all the time, and the tries to stall out, this happens the most when sitting a stop light. plz send response
#128 of 232 LED Instrument panel lights

For the 2004 Grand Cherokee Laredo, where can I find blue LED instrumental panel lighting? When you turn the truck on the dashboard and everything lights up green and I want to change it to the color blue, so how would I go about finding a kit to do something like that?
#129 of 232 2000 Jeep Grand Cherokee Oil pressure/check gauge/air bag/brake lights
Feb 28, 2008 (6:28 am)
I own a 2000 Jeep Grand Cherokee with 160K miles on it. Never had a problem and then it all happened at once. Oil pressure gauge would drop down to zero at a stop and the check gauge light came on. The airbag light would stay on. The brake lights didn't work all the time. I had a couple different shops wanting to charge me a fortune to diagnose and all different things they wanted to replace before even looking at it~ranging from alternators to a new engine. I hooked up with a very honest mechanic Meritage Auto Repair in Auburn, CA who got me fixed up in no time.
1. The oil pressure going to zero and the check gauge light: The oil pressure switch was sending faulty signals and needed to be replaced. That problem solved.
2. The airbag light: The connection had come loose so he reconnected it. That problem solved.
3. The brake lights not working: After changing bulbs and it still not working, a friend who is a mechanic looked at it and noticed the prongs on the connector wasn't lining up. He straightened them out and now they work. Another problem solved.
I was blessed to find honest people to fix our Jeep and it didn't even cost $200. If you have any of the above problems, check out the things that were fixed on ours to see if it will help you. I see a lot of people replacing oil pumps simply because the auto shop thinks it might work. After checking that all your fluid levels are where they should be, try the switch ($40-$50 part) and connections first.
God Bless your day!

I have a 2001 jeep cherokee with aprox. 160000 kms on it. when the engine reaches running temp the oil gauge drops when idling and then goes back up when running also the temp gauge goes up for a few seconds then drops down. does any one know what could be causing this. I havn't seen any signs of any leaks
