Hope the original Poster here got his/her problem solved. Looking over several old threads related to power locks/windows not working, I discovered a new "somewhat" problem with my 2004 Vibe GT, 127k miles daily driver. This is more of an FYI but want to share it with others if it ends up becoming a problem down the road.
Now that summer finally arrived up here in the mid-west, I' find myself driving around constantly with the windows down all the way. Blowing my hair around (the 50% that I still have
) doesn't bother me a bit and feels good while driving. So just yesterday after I parked the Vibe and walked into the house for a minute, I needed to come back out and get something out of the vehicle. All the doors were locked! No big deal as the FOB was in my possession and the windows were still down so I could get in the car no matter what. I didn't recall "locking the car" upon exiting it, so that had me baffled. Here's the real mystery though ....... with the windows down I simply reached into the car and "manually" pressed the power lock switch on both drivers doors to unlock the entire car. NOTHING happened ! Toggling it the other way and you can hear the lock solenoids work, BUT switching to the unlocked position nothing happens. I repeated this several times and was unsuccessful at unlocking the car. Then I tried a different approach. I manually flipped the lever (not the electrical switch) on the passenger side door to mechanically unlock the door, which worked. Then when I operated the electrical switch to unlock the rest of the car ... it worked !!!
So somehow, the switch was deactivated momentarily and by me mechanically unlocking the passenger door "reactivated" it and it started working normally again. FYI .... the factory FOB works and has always worked. The unlock switches (both) were somehow temporarily disabled. Thought I'd just share this mystery and I'm sure there have been others with similar phantom issues.
