2000 Blazer. The button on the dash and the remote works fine for opening the rear window. The push button on the tail gate does not. I looked at site and didn't see any of the same combinations. Any simple fix out there for just the manual operation? Thanks in adnavce for the help. Mark

 

I believe that this button is just another electrical switch. You will probably have to dismantle the tailgate/liftgate and test the switch for proper operation. It is possible that something has happened to the wiring.
