Default Sunroof Issue

Hey all,

My sunroof switch that points to the back of the car will only work after you crack the sunroof and close it with either the middle or forward parts of the three position switch. Everyone I have talked to has said the sunroof may have lost it's memory (like the driver) and needs to be retaught.

Does anyone have the procedure handy and can share it with me.

Thanks!! T2

Speaking of loosing memory.. My girlfriend was trying to open the sunroof in the 965 the other day and told me I was a dumb a$$ for not knowing where the switch was located ??

Is it like the windows and retraining after a battery disconnect? Press and hold the switch in one direction for a few seconds. Press and hold in the other direction for a few seconds. I have no idea and just a thought.

Tom,
I would suggest sending a PM to Firehawk99 and/or Porsche52.
They are 2 resident Porsche experts (or in the P!g Pen, grief counselors).
I'm sure they can help.

60 14 15 Re−teaching the lifting/sliding roof drive
It is necessary to re−teach the lifting/sliding roof in the event of emergency operation or replacement of parts on the lifting/sliding roof (seals, sliding−roof drive) or if the entire system is replaced. The data of limit positions and characteristics are stored and are retained even if the battery is disconnected.
Teaching lifting/sliding roof drive
1. With the ignition switched on, press the lift button and move the lifting/sliding roof drive to the "raised"
limit position.
2. Press lift button again and keep depressed. After around 10 seconds, a complete cycle takes place from
the raised limit position to the positions "lower  open  close". Teaching of the characteristics has been
completed after this process.
Note
The lift button must not be released during the entire process. In the event of a restart, the
lifting/sliding roof must always be moved to the limit position first.
·
3. If the lifting/sliding roof drive should move back in Item 1, then the closing force limitation function has
responded (lifting/sliding force drive was taught). The open button must be re−taught in this case.
Teaching lifting/sliding roof drive
1 Press the open button until the sliding roof stops. Then release the button. Press the open button
again until the lifting/sliding roof drive stops again. Then release the button.
2 Press the open button again and keep depressed. The entire process takes place after approx. 10 seconds:
"close − lift − lower − open − close".
