1996 Chevrolet G Series Van (G10) Q&A

1996 Chevrolet G Series Van (G10) Question: doors will lock with power door lock switches, but will not unlock

doors will not unlock with any of the power door lock switches (driver, front passenger, side or rear door). I replaced the driver's electric door lock switch - no help. The 25A accessory fuse is good. Any suggestions? -
Answer 1
change the doorlock relay. to find it just keep hitting the switch lock/unlock listening for the clicking sound. Once the relay is found. If you have a test light you can Test relay by clippind the aligator clip to ground. while you flipping the switch lock/unlock take the pointed end and touch the prongs on the relay. hen the test probe lights up to you flipping the sitch in lock/unloick then the other side that doesnt light is either the bad side or ground. HaHa you found the problem no your a tech -
