Porsche Cayenne -Blower motor ?

[jdw1222]

2014 Porsche Cayanne - Blower seems to have stopped working completely

no air at all . Was going to replace blower motor unless any other ideas. Fuse is good

Test the wires to it for power and ground instead of shotgunning parts at it. Does it use a blower resister? Wire fall off the back of the switch?

Most likely the motor. They're a fairly common problem.

thanks! that what my internet search seemed to indicate. At least it looks like a pretty easy swap

 

[jdw1222]

this youtube video was helpful if anyone else has this issue

You made pretty good time!

 

[jdw1222]

yeah, Hopefully this one last a while. Its an aftermarket blower that was only around $75

 

[jdw1222]

so I have lost air again. the fix Lasted a couple weeks and now nothing? Is it likely the new motor has already failed? (it was an inexpensive aftermarket motor) or do You think I have some other issue going on?

Do you have Durametric or VCDS?

Step 1: Remove blower motor
Step 2: Test blower motor by connecting directly to car battery, or some other 12V source capable of powering the fan.

You should have done this with the old one before replacing it.

Alternate method involves testing the blower motor in place by unplugging and wiring directly to the battery.

I have the icarsoft diagnostic tool

Do you have Durametric or VCDS?

 

[JC1]

Does it have a blower motor resistor available as a separate part?

 

[jdw1222]

Swapped out a replacement motor and it is working again. Hopefully this resolves the issue.

First gen Q7 is the same. I wouldn’t bother with a cheep one get a genuine part fitted so it’s got 2 years warranty

Sounds like you’ve got the right part. Ive used an aftermarket motor once before and it had a whine to it that the oem did not. Besides that it was way cheaper and worked great. For me, if I were to replace it on my own DD, I’d stay high-end on the aftermarket or just go oem.

 

[jdw1222]

Replaced with another aftermarket this time which is around $80. If it fails again i will go with the genuine VW which looks to be about $250 vs the $400 porsche motor

at least the labor isnt very difficult

 

[jdw1222]

Lasted 1 day and not working again. Going to try genuine vw part unless any other suggestions. Not sure what else to try

 

[meep]

Crazy. Have you tried putting power to these motors when they fail to see if it’s really the motor? Could it be an electronic controller overheating and tapping out?

 

[jdw1222]

I might go ahead and pull this one and try to test The plug has 4 prongs. any idea which one to power and ground?

I dont have a wiring diagram for this car but the larger terminals are generally used for main power and ground. I would suspect a blower relay is failing.
