Anyone had their VCM replaced ?

They started at the latch on the rear left door . Even switched out a latch on the door and same thing. That is when they found the VCM problem. My truck has had alot of after market wiring done for racklights,stereo,etc. This was done before I bought the truck. Tech said he found a rats nest of wires up under the dash. My after market rack lights have never worked since I bought the truck early this year. I have power to all three over head switches but not lights.
