Was thinking body contro module mite be acting up but after web searching looks like thats not involved in window circuit.
any help appreciated! Red an yello wires mentioned above
Have you check your wire harness where it enters the door? Common problem on our rigs with their age, the wires fray from the movement of the door and short or even break causing “things” to stop working. Worth a look. Good luck.
