How do you change the courtesy lights on the side mirrors?


Recommended Posts

I have a 2004 Cayenne S. The downward facing courtesy lights on both side mirrors are out. I have scoured the Internet and haven't been able to find any good instructions on how to get to that light bulb in order to replace it. It's seriously driving me slowly insane... generally I consider myself pretty good and figuring things out, but I really don't want to break a mirror in the process of replacing a $.92 light bulb.

Any help would be greatly appreciated.

Hi,

I am not certain, but this may be one of those deals where dome prying with a spatula is involved, or complete removal of the visor? I have the same vehicle, but thankfully no issue with the light.

I have attached a PDF file that covers just about every light in a Cayenne. Did not see this one , but maybe others would give you an idea of how this one may come out? It is 149 pages long so use

search in Adobe to help..Or just flip through it. Be patient as it is about 2 MB!

Good luck!

Grab the actual glass portion of the mirror and gently lever it out from the inside edge with your fingers.

The glass will come forward and disengage from inside the housing revealing the globe socket behind it.

Be careful when the glass releases and not to pull too far as there are the heater/dimming wires on the back of the glass. ;)

Thanks guys! I was able to pop the mirrors off as you instructed (a lot easier than I imagined) and replace the bulbs (old ones didn't look burned out). However, they still don't light up. The mirrors move as they should, so I know power is going to them, but the lights never light up. I tested every fuse using a multimeter, so that's not it either. If anyone has any ideas, I'd love to hear them... in the meantime I'll be hunting around for a solution.

The power supply that moves the mirrors is not what lights up the bulbs.

Confirm that you indeed do have power to the bulb contacts in the lamp socket with a multimeter. Also check the return path ground is ok (A wiring diagram would be handy at this point).

If no power at both sockets then you may have a programming issue.
