Help- Doors Wont Lock/unlock

bimm3r_c · 02-08-2011, 05:53 PM

Need help guys, My driver side, pass side, LR door are all in lock position and will not respond to the remote lock/unlock. The only door open is the right rear door.

The central lock will not work...is there a fuse blown? i cant locate it?..

edit: i found fuse 56,57.,57 is blown. replaced them both. It worked for 2 tries..then went out again. Is this a door actuattor issue for driver and passenger side?

UPDATE: After the SIB, i replaced fuse 57 with 20A. No issues so far. Ite been two weeks...

I've changed the fuse to a 20A for 1 month, now its blown again, time for a 25A fuse? Or something else may be wrong?

i think you need to replace the door actuator, but i can't remember how to figure out which one is failing.
iirc it is best to replace them all?
do a search on here, because there are a few threads outlining in detail as well as pictures.

do not increase to a 25a fuse, in fact, after you fix the problem, i would go back to a 15amp fuse.

^ +1 You don't want your wiring burning because it's carrying too much current. Much cheaper to replace 15-20A fuses than wiring in the doors.

I had my actuators replaced by the dealer as a warranty repair last week and they put 20A fuses in.
