Sunroof not opening

Hi all

I tried to open the sunroof recently while in slow-moving traffic - a nice sunny day. It's too noisy, I find, if it's open when at speed, so it's only been opened about 20 times in the last 15 years.

If I press the open button, the sunroof motor starts and it opens a crack - but that's it. When I press the close button, the sunroof motor starts and it closes completely.

Broken cogs/gears, perhaps? Or insufficient use, maybe?

Any thoughts appreciated.


 
Hi Matt,
My costly experience may help you. In the middle of France I opened my roof. When I came to park the car and close it. Nothing! Try, try as I may it refused my requests. Out came the spanners, unzipped the roof and contorted my 76 year old body to manually close the thing. On return to UK I visited my local PC feeling sure the motor had failed. After a couple of hours routing about it was discovered the switch was faulty. Cost of switch approx £45. Total cost £300. Ouch. Most of the cost was diagnosis.
Suggestion....check the switch before anything else.

Thanks Richard

Diagnosis is usually the difficult bit, though I think my switch is working - the sunroof tries to open but won't. Cogs, rails and teeth I suspect.

Hi Richard

It turned out to be a broken wind deflector - its shattered bits had jammed the rails.

All fixed at the 48k/MOT - see my post - 'Reading OPC - special offer'

Quite a common problem, one side of mine broke a few weeks ago. Apparently you are not meant to operate the sunroof above a certain speed (30 mph?) to prevent the hinges from breaking.
 
To be honest, John, I 've used the sunroof about once a year since I bought her - and then only in stationary traffic. It's just too noisy at speed.
