Power mirror motors can fail over time due to the elements. The Cayenne has two motors in the mirror assembly. One controls the mirror adjustment and the other controls the mirror assembly folding in and out.

Thankfully, diagnostic scanning can make troubleshooting problems with the system quite easy. Using the factory Porsche computer or Durametric software, you can easily test the various components and isolate any trouble.

Note that replacing the mirror adjustment motors is a simple procedure that should not take more than an hour. Replacing the mirror folding motor requires removing the whole mirror assembly. This is a bit more complex and requires removing the door panel. Please see our article on Front Door Panel Removal for more info.

Begin by pressing the left side of the mirror (green arrow) as far in as it can go and then pull the mirror off at the right side as shown here.

Joe Comments: I've replaced the mirror following your guide, thank you. My original locked in a half way position. However, with the new mirror it will not fold. Is there a reset procedure for the door module? Thanks

  Followup from the Pelican Staff: See the first step for removing and replacing the mirror glass. Give The Pelican Parts parts specialists a call at 1-888-280-7799. They can figure out what part or repair kit you need.

Targa Comments: Previous owner hit mirror and had someone repair/paint/etc.. They did not do a good job on the fit and seal so air flow noise comes thru on inside. I plan to remove the mirror to see if I can reset in proper position. It appears I can remove the inside mirror switch cover and try to make adjustments without taking entire door panel off i.e. at this point I don't plan to replace mirror, just reset and add insulation as needed Thanks!
