Lly electrical problem

[boskokudra374]

Recently purchased a lly that is having electrical problems. Nothing is responding on my passenger side . Mirror , window motors and switches where replaced and both seats aren’t working. The driver mirror automatically goes into curb mode when the truck starts. I replaced the mirror switch and the master window controls and cleaned the switch connector. I just recently replaced the BCM on the truck and nothing changed.

I had something similar happen when some of the pins in the bale connector backed out and weren't making good contact

Are you referring to the door harness?

Can you communicate with the PDM using a scan tool? I am guessing either the PDM has problems, there is not power to the PDM, or the data bus has problems.

My drivers side mirror is also moving when you turn the key to start. Isnt in "curb view assist". Haven't been able to figure that out yet, if you do let me know please

here is a crazy question. do you have an aftermarket radio in the truck? I had one in a truck I purchased and there were all kinds of electrical gremlins. When I unplugged the radio everything started to work fine. Cost was zero for repair but a few hundred for a quality radio
