Driver's power door lock not working

The driers side power door worked then it began intermittently working. Then it stopped working.
All other power doors work fine with remote. This is the troubleshooting I performed.

1. Did the check on the wire harness to make sure there is a firm connection.
2. Replaced the door regulator with a new one. Also tested it on other side to confirm it works.


Next I need to test the wiring on the harness to make sure it has the correct voltage.
Does anyone know what each wire on this harness is and what voltages should be expected?
Or any other advice to fix this issue would be appreciated.
Thanks

 

Do you take your doors off at all? If so, I'd really focus on the wire harness. I had a similar issue with power window. I thought I had confirmed over and over that I had a good connection in the plug, but I eventually discovered that when I'd connect the harness, one of the wires would slide back just enough to create a loose connection, resulting in my window working intermittently. If you replaced the locking actuator in the door, and all other door locks are working properly, and you mess with that harness from time to time, that is what I'd focus on. Not sure what your harness is like on the '08. I hate the harness I have on my '13. They updated em in '14+ to something that is much better IMO.

 

The front passenger door lock gradually quit on mine.
It was not a power problem. It is a binding in the internal lock mechanism.
When I lock/unlock it with the button inside, I can hear a slight squeaking inside the door in the area of the latch. It's just enough of a bind to keep it from working electrically.

See if your could be a similar issue.

I hate door work, so I have not gotten into it yet.

 

 

 

I would start by replacing the door actuator. I've had 2 of them fail on my 2009 JKU with the symptoms you described. Driver's door actuator replaced under warranty, and rear driver side door replaced by myself after warranty expired. The actuator failing has been a known common problem on our JK's. When I looked up the replacement P/N for my rear door, the P/N has had 10 revisions to it compared to my factory actuator....so FCA knows about this problem and seems like they have been working with their supplier to get it fixed. Supplier changes to a part requires the part number to be revised.

 

I have (x3) and the reason I think its not actuator is there's no power to tan/L green when I try to unlock and there is to tan/white when I lock. I saw a thread on another forum and they talk about rebuilding the TMIP (fuse box essentially). I'll see if I can get a link to it because it had some very interesting info....thanks for you help!!

 

Here it is....

Let me know what you think or if it don't work let me know and I'll see if I can get you there some other way....Derek

 

I haven't taken off the door before.

One more thing, the windows all used to work and I can't recall a specific point in time when it just stopped working on that one window.

Thanks for the reply!

 

Thanks for that feedback, I'll be sure to pay attention for any noise next time I'm in the car.
