95 Yukon Power door locks

[dgoodman1968]

Hello, I have a 95 Yukon that the power door locks work intermittently. The drivers seat also does not work. The thing I find odd about the locks is I recently had a battery die, and I took the opportunity to convert to top post cables. The locks had the same issue before I converted so I dont think thats the problem. However I did notice when I removed the battery cable for a few minutes and then reconnected the locks worked as they were supposed to for a day or so then they dont until I disconnect again.

If it is a 4dr I would say relay contact are getting aged and holding back electricity to the locks. If some work more then others, the others may just be worn out or burned out on the motor contacts.

It really sounds just like old contacts at different electrical points holding back electricity. Are you 2-4dr?
