Note: I had the door lock relay/problem fixed during the recall back in '92 or whenever.
If I keep pushing on the door lock buttons the door eventually starts to lock ..or .. I can use the key and it will unlock or lock all the doors at once.
I also have a remote control (3'rd party). If the door lock buttons are acting up - the remote will not activate the door locks either. I know the remote was wired into the wiring harness for the door lock buttons.
What I find wierd is how the key will open all the doors - you would think the wire for the door key switch would be the same wire as for the door button.
Any suggestions appreciated.
