After reinstalling my door panels following speaker installation, my power locks aren't working right. Here's what's happening:

Passener door switch:
Will lock, but won't unlock

Driver door switch:
Won't do anything

I checked the fuse and it looks fine. Anybody have any idea what might be going on here? It definitely feels electrical.

 

Does your truck have remote keyless entry ?

 

No it doesn't have keyless entry.

 

Pop the driver side switch out or pull off the panel, should be a bad connection at that switch.

 

Well you know the connector is one of those locking snap-in types and it was secured properly. I disconnected and reconnected it just in case, but it didn't change anything. Do you think the switch itself might be bad? Could the problem be somewhere else in the system?

Dodge wants $73 () for the switch assembly, so...I'm hoping I can fix this some other way.

 

If i could figure out how to post pictures , i would show the wiring diagrams. If all you did was pop the panels off, install 2 new speakers and reinstall the panels, it shouldnt be too hard to find.

 

$73? Gee! Ford only got $18 each for the power windows switches for my dad's 93 Lincoln LSC a couple of months ago.

 

Guys, I really need some help here. I need to figure out what's up with these locks. Please help me troubleshoot this.

Perhaps I could use the passenger side door panel on the driver side door to determine whether it was the driver side switch that's faulty. In order to do this, I'd need somebody to help me figure out how to jumper the passenger side door plug so that the truck thinks there's a functional switch attached to that door.

 

I'd guess you knocked/pulled a wire loose somewhere. Go back into your doors and make sure the wires are seated in the plastic connectors.

I don't know if this will help you but on a 2004 the lock/unlock switches send a ground signal to the instrument cluster computer. The signal for lock and unlock are goverened by the value of the resistor but the manual doesn't give the value. Both lock and unlock show the same path to ground but through different resistors. The book also shows that the driver's and passenger's switches send their own signals to the instrument cluster computer (the switches are independent of each other). So on a 2004, you can't "trick" one switch by jumpering the other switch.

 

I'm thinking it's basically the same in the late 2nd gens.
Switches do nothing but tell the computer to unlock or lock the door.

Hopefully you didn't short something and kill that portion of the computer.
