I was wondering if anyone has ever had this problem?? I have a 99 max se and I tried locking the doors with my remote and all doors lock except the passemger door. Anyone know what this could be????
Please help, Dont wanna pay dealer an arm and a leg to fix.

 

does the window switch on that door work?

If not, the wiring harness came loose. Or maybe check fuses.

 

I had that exact problem except with a different door. I'm not a wiring guy but all I know from my friend that fixed it was a blown fuse.

 

If it's not a blown fuse, try taking off the door panel and cleaning off the lock mechanism. Mine stuck occasionally, and that helped it.

Now this is a dealer stock alarm, All 3 doors lock except for that one.
