I've been having issues controlling power locks on the driver side - locks work properly on passenger side and I can unlock the doors from both sides but I cannot lock the doors from driver side - this just started .. Any suggestions ????

 

Forgot to mention problem I'm having is on a 2000 Cherokee

 

I have something similar happening, but have had time to get the meeter out to check the wiring. I was thinking it was my aftermarket alarm system as by hazards do not work either.

I suspect that the issue is probably in the wire bundle that goes to the door.

 

Its def not broken wiring in doors - i did have some but rewired ... It just does not make any sense ... Just stopped working all of a sudden - cannot lock but it will unlock & passenger side works fine .. Im stumped

 

That is what happens when you leave the key in the ignition. Maybe something with the wiring logic. It thinks the keys are in the ignition.
