I have a 2004 Grand Cherokee Limited. I have tracked down an issue in the driver's side wiring harness where the power windows, power mirrors and door lock is not working. Inspecting the harness, it has clearly been worked on before as there are large gobs of solder on three of the wires. I am thinking that replacing the harness might be wider than working on the mess.
Unfortunately, I am not sure where I can get a harness and I assume there is one that goes from the fuse box through the door post and into the door. I won't need an entire harness.
Any thoughts or recommendations on how to proceed?
