Right rear door of my 2002 Trailblazer does not unlock when using the key fob to lock and unlock. is likely an electrical issue or mechanical? Any ideas help! Thanks. GS72hotrod

Best way to find that^ answer is to pull that door panel and have a look .
Either electrical or mechanical requires that panel to be removed anyway .
Heck , it might just need a bit of lube . ;)

There’s two poles that connect the handle to the lock, pull the interior handle and if the door opens then that pole is disconnected, press the unlock button twice on the key fob or press the unlock button on the door panel and see if that allows you to pull the door open. Either way it’s a free fix, the ring that keeps the poles held in place falls off frequently it’s happened to me too.
