Need some help with failed window/lock switch
I'm out of ideas. I just replaced my driver side window regulator and reconnected the switch panel to find that the doors won't lock and the windows won't roll up or down. The crazy thing is I can move both mirrors just fine. I replaced the fuse for the LDCM (#33) and still no luck. The only code it's throwing is a U1160 H code. Key fob unlocks both doors fine and the passenger side controls lock and unlock both doors as well.

Pop out the accordion tube and disconnect both connectors. Inspect all the pins Look for bent/burnt/deformed female pins. Repair as necessary. Reconnect and try again.

Popped out the wires in the accordian thing and inspected them. Still no luck. Jiggled the wires all throughout and nothing as well. I'm not getting any codes now either. I replaced the door control module with one I bought from someone on here and same thing. I can move the mirrors but can't lock the doors or roll the windows up. Is it a bad switch?

The DCM has TWO fuses. You need to physically check BOTH. Make sure that they are in good shape and not loose. Make sure that there is power at both fuses with a METER. Measure the same voltage at the plug on the DCM and make sure that it is full battery voltage.
DCM-L Mini fuse 33 10 amp
PWRFDL Mini fuse 34 25 amp

Ok I nailed it! By sheer curiosity I plugged the passenger side switch into the drivers side DCM and now it works (window rolls up and down and doors lock). So I'm down to either the wiring or switch assembly.
