What would cause my 2008 Chevy Avalanche stop unlocking/locking only one door...the drivers side...with remote/keyless entry and the lock/unlcok button on the door panel. It will only lock/unlock manually or with the key inserted into the door itself. All other functions on the drivers’ side door work such as the window, seat heater, minor adjustment etc. The vehicle will still remote start but if you open the driver side door the alarm goes off. Any help would be so appreciated.
