2003 Yukon Auto Door Locks

[TxTruckMan]

In my 2003 Yukon, the auto locks intermitently only unlock the front doors. It's the same with the remote or hitting the unlock button inside the door. The only way I can open the rear doors is with the manual door lock. And I'm SOL if I want in the rear liftgate.

 

It was happening pretty infrequently over the last 2+ years until this last week. Now it's very frequent, though still not all the time. This is a major problem as I have twin 2 year olds that sit in toddler seats in the back, and we carry our stroller (and other stuff) in the far back.

 

It appears to happen more frequently when it's cold or wet out, but that could be my imagination since those are the times that piss me off the most.

 

Anybody seen a similar problem and/or have a solution?

 

Thanks for the info!
