The motor continues to run after the the sunroof is completely open. I have to click the switch to get it to stop.

Relay? It is a brand new motor.

Thoughts?

If clicking the switch stops it, then the switch may be the problem. I think I read somewhere that the console warps slightly and makes the edges of the buttons stick. You can probably open up the switches and clean them out, maybe file the edges a little and it will be fine.

Same happens to my drivers side window, there again I kinda like it that way.. Poor mans auto down as long as I remember to turn it off.. One day I'll fix it... one day..

Hopefully before the motor overheats and causes an internal door fire.

Doesn't it have auto down already ? Mine does, although somewhat peculiarly, it will only do one window at a time - i.e. if I press the passenger window button first, and then the driver's side button subsequently, it first rolls down the pasenger window all the way, and then starts on the driver's window next. I have to hold the buttons for maybe 1-2 seconds for the auto feature to kick in.

Cheers,

Trying to get back on topic. THe console is not warped and not sure how test theat hypothesis.

Thermal protection on the motor turns it off. You hear it clicking in the door as it retries after cooling off.

But back on topic.. the switches themselves can warp just enough to catch. A friend of mine had the same issue, took the switch out, gave it a good cleaning, trimmed it down with an exacto knife and it's as good as new.

Okie dokie. I'll take a closer look.

Another part of cleaning is the internal cleaning of the contacts and rocker mechanism (pivot point). I've never had one of these apart, but from reading up and working on other switches, I would imagine that there are several ways for them to fail, and cleaning will fix almost all of them.

Make sure you check this out as well.. Some good info.

Do all 928s have this?

If they do then that's good. I just remember reding an article about a 60's Camaro that had a sticking convertible roof motor 9stayed on wafter the foor vas retrected) and caused it to catch on fire, burnign the back half of the car.
