I dnt know if your problem is fixed yet...but my dad had the exact same prob when he owned his 97 taurus GL...he had to change the courtesy light switch in both front doors, the prob was the switches would stick open....unfortunately this involves removing the door panel to get to the whole door latch/actuator assembly since the switch is in there, but hopefully sprayin lube will help it....it looks like this to give you an idea http://info.rockauto.com/Motorcraft/...tml?SW5195.jpg
I haven't had a chance to spray the latches yet. That's next. I also strongly suspect the driver's door ajar switch and already had the inner panel off. I couldn't reach the switch connector to take it off, so I unbolted the latch mechanism but couldn't pull it out without a major disassembly of the window tracks, mechanism, etc. So I gave up on that & buttoned it back up.
I have the service manual with wiring diagrams, connector pin outs, etc. Next I disconnected the connectors at the GEM
(located at the fuse junction box under the dash) & tried to check continuity to ground for the various door switches (they provide ground signals to the GEM
when the door is open). But, I couldn't get the signals to change to closed state (I already found mistakes in the manual and may have been chasing the wrong wires). I'm pretty frustrated that I haven't pinned the problem down yet after several hours trying.
In the end it's either the switch sticking like Bull Geek said, bad switch, or a bad GEM
. I hope Bull Geek is right! I'll post again when I know more. Thanks for everyone's input.
