Hello, I have a 1991 C1500 and ever since I bought the truck the doors would lock but not unlock. This has been baffling to me because the lock/unlock just switches polarity. At first I thought it was the switch itself but both doors will function perfectly locking but does note even make a noise like its trying to unlock.
I have the wiring schematics but have no idea where the wires actually are (which wires are the correct ones). The only thing I can think of is that maybe the previous owner messed with it. I think if I knew where the wires were I could trace them down and look for any issues.
If anyone has any useful information it would greatly be appreciated. I am perplexed.
