Today, my 2000 Cruiser locks decided to stop working (using the keyfob). The battery of the keyfob was weak, so I replaced it and now the keyfob will not lock the truck. I can get into the truck, shut the door and lock the doors using the switch on the door and hit the unlock botton on the keyfob and it unlocks the doors. I tried using the key in the door and it doesn't lock the doors either. It acts like there is a door open. I checked the switches at each door and they appear to be working correctly. Is there another microswitch in the door latch mechanism that senses when the door is shut (was thinking maybe the switch I was looking at was purely for the dome lights). Any thoughts?
