Ignition switch is on and doors will not close. They open fine but no power to motors for closing. Any suggestions.

there are 4 limiter switches and 2 relays, I take it the 2 limiters are working to "stop" the doors when they open, and the relay works for the opening part, but no power for the closing operation, check the relay, the cluprit one is usually the one right below the voltage regulater, looks like a 1.5" square metal box plugged into the R/S harness for the lights, its on the same wire as the relay switches., and its a $3.49 part at pep boys or autozone, whereever.

you may want to hook up a multimeter to it to test for current and continuity,

How old are the relays? (under the left front fender)

The relays are original and I'm confussed about the relay under the voltage reg. That's shown as a horn relay? Does that tie into the light system also?
Thanks

Check the circut breakers near the relays.
They are small and have two posts on them. There is either one or two of them.
That's the only thing that ever went wrong with mine.
The horn relay is underneath the voltage regulator. There are some fuseable links that connect to it and it's a main power connection for the cars circuts.
Check your grounds on the realay panel too.
I wish I could be of more help, but luckily, I haven't had to learn much about this system.
I have a wiring diagram for the headlights on my first gen camaro page.

It seems you're indicating the doors will open and stop correctly. Since power is getting to the motor to open, this would indicate the problem is in a relay or the headlight switch. possibly a disconnect or bad contact depending on the degree of hacking done on your system. My switch has been a little screwy lately with having to make sure it hits the detent for closing the doors. Having reworked my RS doors, I would have to say a relay would probably be the bet based on what you're saying. They are neccessary to get the voltage on the motors reversed until the limit switch shuts them off. A voltage meter should give you an idication of current flow.

Thanks for everyones input. Although the relays appear to be working when I manually energize them maybe its time to replace all three. I did replace the horn relay but that didn't fix it. I need to find the wire that powers the relays when the ignition is on (light switch off) and make sure that wire is hot. Thanks again and I'll keep you posted on what happens. If it's like most things it's so simple after you find it you can't believe you missed it to begin with.
