Has anybody any experience with the following scenario?
My power locks recently began to work incorrectly, as follows:
The switch on the dash correctly locks and unlocks all of the doors.
The key fob unlock button correctly unlocks the doors, but the key fob lock button will not lock the doors, although the alarm system DOES get armed by the key fob lock button.
The fuse on the circuit has also blown once since this started happening. I have replaced it and it hasn't re-blown yet.
I do have an aftermarket remote start unit that installed which also activated the lock function, which might have some effect...
I'll be very grateful if anybody can provide any insight as to why this may be happening, and perhaps what component in the central locking system might be suspect.
Thanks in advance!
