Sunroof will not open

Hi,

On my 83' I replaced the SR switch and now have power to it. The motor spins about 1/8 turn and stops either forward or back. I pulled the motor and gear out and ran 12 volts to it. Jumped around like a frog, but spun fine. Is it possible the motor has lost it's torgue or is there something further down down the road I need to check. Thanks.

With the sunroof motor out, does the sunroof slide easily forward and backward?
There could be a misalignment or perhaps something in the sliding mechanism is jammed.

Also, while the sunroof motor is out, check the sunroof transmission for free movement as well.

Thanks, I will give it a try. It also leaks badly and is obviously not in it's home position. I will try and remove it.

My recollection is that with the sunroof motor out, it can be easily moved. If not then removing the sunroof transmission will allow you to.

Once it is straight the motor an transmission will probably work without issue.

I sent a reply yesterday but now do not see it so I will try again.

I removed the motor and gearbox, but cannot move the SR. It dips down at the rear about a 1/2 inch and is snug up front. Should I remove all the trim around the SR to gain some access ? Thanks.

You may need the manual, but Wally Plumley (an encyclopedia of 928 knowledge) posted this, that may help: members.rennlist.com/pirtle/zbody_sunroof.txt

You sum Wally's contributions to the 928 community so well. By the way, where is Wally? He was a regular participant of the old board, wasn't he? I was hoping to get his thoughts on my head gasket project. I figured he'd know the torque procedure I was searching for off the top of his head actually.

You post the topic/question for him, and I will let him know it is here, perhaps we can entice him over.
