Drivers side power door lock question??
 

On my 97 Blazer 4x4 the Power door lock only unlocks the doors. Sometimes it will lock them but that is rare. I can lock & unlock them with the remote. Also they will not lock from the passengers side.
I'm assuming I have a bad main switch on the drivers door. Has anyone had this problem? If so what have you found? If that is the problem how the heck do you get the door panel off. I never figured out getting the door handle clear.
Any help would be appreciated. Thanks
