I have a 1999 with power door locks and barn doors. The rear doors will lock but not unlock. I have power at the contact point in the door opening for locking them , but I don't get power to unlock them.
Has anyone else had this problem and if so where was your lose of power .

Great question Dondobe. I do not have an answer, but a similar problem with my 1999 Suburban. The drivers side door is the only one that locks and un-locks reliably either with the keyless remote or the door button. the others are hit and miss, wich is not a good thing in my opinion.

The rear barn doors only lock and unlock with the key.

I hope someone has some insights for an easy fix.
