Some of my PW and PL work. Some don't. Thanks to ELVATO for showing me how to get to the switches for the PW and PL. I've jumped the switches and get the same so I don't think they are a problem. Here's what works and doesn't:

Driver controls: can work all PW, can't lock, can unlock

Front passenger: can lock and unlock, can't work window

Driver side rear door: can't work window

Passenger side rear door: can work window

Is this a relay/fuse problem or wiring? I just had a 7-pin RV adapter installed from the front to the rear. (Even though the Exp had a factory tow package, it only had the 4-pin adapter. The dealer and trailer store both said it had to be wired from the front back.) Could the trailer store have caused the problem when wiring for the adapter and brake controller?

Thanks ahead for any advice.
