Ik haalde mijn contactsleutel uit mijn Carrera 4 van 2002 (996). Daarna ging het linkerraam voor de helft open uit zichzelf. Ik heb toen met de raamschakelaar het raam verder opengedaan, maar krijg het niet meer dicht. Al eerder werkte de schakelaar van mijn schuif/kanteldak al vreemd. Schakelaar werkt ook niet meer en geeft rare commando,s af op schuifdak. Wie kan me er iets over melden. Volgens mij is het een elektrisch besturingsprobleem.
Alvast dank voor jullie deskundige reacties.

Daar lijkt het wel op.

ok effe serieus:

First thing that comes to mind is water in the door. If water is present this initially causes weird window and door lock behavior. Give the door a shake listening for any water noises. Check for dampness at the the bottom of the door. While you are there check for any dampness under the seats, particularly the passenger seat. I do not think you'll find any it is just a precaution.

Barring this dropping is a comfort (komfort in Porsche speak) setting -- which I do not believe that it is -- it reads like the door lock assembly (which controls more than just the door lock) -- is bad.

While I do not think it will help, you can remove the key, turn off all electrical loads, and disconnect the battery. Follow battery disconnect (and reconnect) procedures. Leave the battery disconnected a few minutes, or step on the brake pedal to remove any residual electrical power.

Be sure if required you have the radio security code.

After you reconnect the battery, you will have to set the window limits. Lower the window using the lower button. Release the button. Press and hold the raise button until the window is all the way up. Continue to press the raise button for 5 seconds after the window is all the way up. Release the button. Done. Repeat for the other window.

You will also have have to recalibrate the e-Gas. With the key off and your foot off the gas pedal, turn the key to the on position. Leave on for 60 seconds. Turn off the key for 10 seconds.

If you want to avoid the hassle of the battery disconnect, you could just try resetting the window limits.

If the battery disconnect or the window limit reset doesn't help, to id the cause the of the behavior you probably need the car connected to a Porsche diagnostic computer. The tech can query the car's security system which can supply error codes that pinpoint the failing switch or controller. The door lock assembly is a rather expensive item.
