Hello all, I have registered because a friend of mine told me this is the best place for 1st Gen Expy troubleshooting/advice on the internet! Having said that, thanks in advance for any replies, my issue is this. My power locks on my 97 XLT have stopped working when pressing the fob keys or attempting to use the switches on front doors. When you use fob, the running board lights and interior light come on but locks do not operate. If you press to lock on fob, the running board and interior lights go off, but no action on door locks. So far I have checked the fuse under dash (ok), replace all 3 of the relays in dash, replaced both driver and passenger side door lock switches and checked the wiring in the door jambs for any breaks or crimps but nothing. There is no noise what so ever to be heard when pressing the door lock switches to lock or unlock. I was told there is a box under and to the left of the steering wheel that is for anti theft but that would not explain why the locks do not work even with doors open? I'm at a loss, it's a nuisance because this has rendered the rear handle for the tailgate/glass inoperable.
