Gotta hold of a ASC sunroof from a 91 GP SE out of the Junk Yard
Its the one with Three buttons: one for open--one for close---one for vent--also theres a button on there that says ASC which I have know Idea what that does
My question is this: when I press and release the open button it will open automatically untill it gets to the end and the motor continues to run. So I have to press and release the open button to stop the motor----- is there something that I'm missing that allows this to operate correctly----or is this some kind of sensor thats not reading right----or does this use a motor spike reading thats not working
The same for the Vent button
but whats funny is the close button is the only button that works properly: when I press and release the close button the sunroof closes and stops where it is suppose to stop automatically on its own
Can anyone please help me out with this issue , I've went through all of our searched problems I found one that was close but did not have the same problem
If anyone has a service manual that covers this sunroof could you copy the pages and either send them to Jimmy or me. The service manual he has lists a similar unit but not close enough to figure out his problem. We were looking at his yesterday and the only wiring that goes to the sunroof are the 2 wires right to the motor and 3 wires to a proximity switch located in the frame. The proximity switch works any time you pass a magnet near it the motor stops running. The problem is the only time anything is near the proximity switch is when it closes. This is why it closes correctly. The rear bracket is right over the proximity switch when fully closed. There is nothing near it when it is fully open and the bracket pulls away when it goes into vent.

Just got off the phone with a tech from ASC sunroof Co. and this is what he said:
these models were Aftermarket sunroofs, they were not sold to Pontiac for there factory sunroofs.
the way they work is when the magnet located in the moving arm crosses over the switch it tells
the computer module how far to let the sunroof move which he explain in time. then once this time
is reach it will shut the motor off automatically, same way with the vent
So detective Jimmy :worshippy: did he say the board would be bad if it doesn't stop? Could you just running it on a battery cause the timer to be off? Lets hook it up to a running car and see if that works better.

well funny thing you asked, because hes not positively sure it could be the module: he said hes never seen one just go bad
he said you need to check everything else first with an Ohmmeter to be sure nothing else causing this issue.
what there to ohm? a couple of switches that are either open or closed. Did he hook you up with any paper work to look at?
