I have an issue with my speakers on my driver's door and passenger rear doors are not working and doors do not lock in the rear both doors. I got a 4-door 1500, I checked all harnesses on all doors they all good not cut. I check wiring to see if electricity is going through and there is power going through them from the radio out to the speakers but it doesn't make it to the speakers. Rear doors don't lock, unless I manually lock them. I only have the passenger front speaker working. I bought another radio thinking it might be a defective radio and it wasn't. I also plug in an aftermarket radio with an extra ground to see if it was a grounding issue. But still nothing working. If anyone has any information I would appreciate it. THANKS!
