Automotive Forums  Where Car Enthusiasts Go to Discuss Cars Online

Heyy, this is my first post in this forum, nice to meet everyone.

I just got a 2001 Jeep Grand Cherokee Laredo 4x2 with the straight 6 engine and auto transmission.

Since I bought the jeep, it's been running close to perfect. Last night I drove around, got in an out several times and everything was fine. I decided to run and grab a bite to eat, so I got in, and as I was driving, I realized the inside lights weren't shutting off... Thinking that a door may have been open, I stopped and opened and closed all of the doors securely, including the cargo door. The lights still didn't go off, so continued to drive and get my food and head back to the house and figure it out then.
I got home, and I shut the car off, and when I hit the door locks, the doors wouldn't lock. I turned the car back on, the windows will not roll up or down....

OK To sum it all up - the windows won't roll up or down, the lock buttons will not lock or unlock the doors, the interior lights stay on for about 10 to 15 minutes then shut off finally, my car alarm light is NOT blinking (the red light in front of the driver dash), when I put the key in the door and unlock it, the interior lights are not turning on (they normally do, but they aren't turning on until I OPEN the door) - And today the overhead display says DRIVER DOOR OPEN - which I made sure was closed securely...

Any pointers or advice? This is driving me nvts, and monday I'm supposed to get it insured and pay the tag/title/tax!  

By the way, I did unhook the positive terminal to the battery in an attempt to reset the computer - which did not help.  

with the drivers door open... see if you can find the switch that turns off the dome lights...  somewhere on a door jam.. usually with a rubber boot...

push it with your hand.. see if the light on the dash board goes out..

how are the door hinges..  are the doors sagging ???

the electrical systems can drive people nuts..  with just a bad switch..  

Hello there,

My Jeep has been doing the same thing for the past year. After replacing the Electric Body Module three times(because this is what the dealership told me); still the same thing. My jeep has been in and out of the shop every two weeks for the past year trying to figure out this problem.

Does your instrumental panel gauges stop working when the door locks and windows do not work?

I believe that the problem with my jeep lies within the door actuator. If the driver side window lock is not on, then there is a clicking noise on the passenger side door, when you hear the clicking noise, the gauges go down, windows and locks stop working. After replacing the module the first time, the clicking noise was still there so they disconnected the automatic door lock on the passenger front door. Unfortunately, the clicking noise was still there; not as bad with the window lock on. Last night I was driving the jeep, clicking noise started, gauges went down, no door locks or power windows. I started messing wtih the passenger door switch, and window switch. The gauges came up, windows and door locks were working. Needless to say, my jeep is going back in Wednesday morning for this problem. I believe that there is a wire that is touching metal; shortening out everything else. I will keep you posted should the problem get fixed.  

yo JTrentham I have exactly the same problem as urs. Everything on your post matches my recent problem the just started yesterday. I was at mcdonalds drivethrou n i couldnt roll down any windows! It was raining ice the night before and so I thought the door just froze and I just had to give it some time to get the windows working but their still dont work. And that drivers side door open message wont go away. My electrical thermametor isnt working either. My alarm lights dont work WTF. This all happened in one night. I dont have that much money to take it to a dealership, so I really just want to fix everything by myself. If any one knows how to fix all these problem plz let me know.  

the problem...    everything is computerized on that jeep... as are most newer cars...  you move a switch.. it asks the computer to move the window..  

there are several of these CAN busses in the jeep... (Controller Area Network)   one for the motor.. another for the air bag and antilock brakes... and another for the rest of the car.. including the windows and dash ...

to work on these systems...   you need a CAN enabled scan tool..   that has the proper program to communicate with your jeeps systems...

you will need a LOGIC PROBE>... so you don't blow the data bus...  i have had too many cars come in..  that people have let the smoke out of the wires...

and the most important.. a full factory service manual... way over 500 pages... or a subscription to one of the online automotive information services....

alldatadiy.com

or eautorepair.net     both of them have   factory information...

http://www.faxonautoliterature.com/   this place may have the factory service manuals in print... i have not had time to check...  

i have an 04 jgc and it is doing the same thing,word for word. im going to keep trying to fix it myself. if i find any thing i will post. its just after xmass and i cant aford to take it to jeep. if anybody has any luck,let us know plz!

to most of you people the problem is a black ground wire in one of the front doors i fix this issue all the time find it in the wire harness in the front left or right in between when you open it you have to follow it into the hole to the front of the car if you have any questions email me at Shadow11187@live.com  

I am having a problem with my passenger window. It went down half way. So I was told to push it down to see if it was out of line. That was not the case. I hear the motor run when I push the up and down button but the window won't go up.  Any solutions?  

Hello,

If anyone out there is in need of a manual transmission. I recently bought a nv4500 transmission for my 1999 Dodge 4X4. I talked to a Jeff and he said if anyone calls and buys a transmission from him he will give them a $25.00 discount. Pricing was great and service was awesome, shipping was very reasonable! Here is a link t there website: http://www.smartpartsauto.com

replace the window regulator... there are aftermarket versions available for significantly less than factory parts...

there are a few auto glass shops that know how to fix these ... as there is a small part that breaks... that can sometimes be replaced...

this is what the window lift motor and regulator look like in a 2001 JGC passenger side rear door...


 



when the motor runs.. and the window does not move..

the thin steel cable that is wrapped around a grooved spool is usually shredded and tangled beyond repair..


these window regulators may or may NOT be RIVETED into place..   requiring a special 1/4" pop rivet gun..  thats not something everybody has...
