Got an '87 Trans Am and the headlights don't actuate (open/close).
They're intermittent and have gotten to the point that they just stay open.
First, it was one then the other. Later, one would open/close and
eventually they're both open; where they are now.
I don't know much about the way they work and the manuals don't address
'em at all. I believe they're controlled by an electronic controller that's
probably a dealer item, which explains the lack of info:(
Can anybody give me some info or insight on the system so I can stop
looking goofy in the parking lot?
Really appreciate the advice,
Hey, sorry for not responding earlier. My news reader pooped the bed and
I eventually had to start from scratch.
Anyway, wanted to thank you for the link. It didn't help, exactly, but it
did educate me a tiny bit and that was all I needed to motivate me to tear
in to it. And, I think I found the problem; door control module.
The article said the module was easily accessible (it was) but rarely ever
goes bad (it apparently DID). The module's located on the driver's side
firewall above the rest of the wiring with two, weatherproof connectors.
All it does, from what I see, is apply voltage in one direction or the
other to the motors.
A) Turn ON headlights; power goes into module (form ON position) which
powers the motors in forward direction to open.
B) Turn OFF headlights; power goes into module (form OFF position) which
powers the motors in reverse direction to close.
Thanks a lot,
P.S. Happy New Year!
