Sticky switch

Recommended Posts

Got my Boxster last summer and as the weather has turned cold I've found the climate control "+" switch gets very tight in the morning, to the point that if I push it hard enough to increase the desired temp, it doesn't release when I let go of the switch and just runs the temp all the way up. I then have to wait several minutes for it to come back out to the point where the other switches will operate and allow me to reduce the temp to what I really want.

Any ideas on freeing up the switch?

My temp buttons stick as well in the cold weather. I recently ordered a new LCD panel from www.modulemaster.com due to the fan speed display not showing all the indicators on the lowest 3 settings. Included on their site is a step by step diagram on how to disassemble the climate control panel. The instructions for the LCD panel replacement include cleaning of the contacts for all the buttons. I have yet to do this repair, but I will post my findings on how the buttons work after I clean everything while replacing the LCD panel.

Hope this helps a bit,

Thanks. I'll be awaiting your results. I looked at that site but couldn't find anything Porsche listed.

Good luck with the DIY.

On the home page, scroll to the bottom. In the middle of the screen, you'll notice a climate control picture/link. Select that, then on the next page, click on the link to open the PDF of the instructions to fix the Porsche climate control LCD.

OK, I found it now. I'll give it a shot this weekend if I can find the time.

I just finished replacing my LCD panel on the ventilation controls. Super easy with the kit supplied by the vendor that sold me the new LCD panel. I also cleaned all the buttons and it also was easy to clean off the coffee or cola that was spilled on the buttons.
