Porsche Repair Questions? Ask a Mechanic for Answers ASAP
Can you tell me what model Porsche you have? The info I have only states it is a Porsche. Thank you.
Yes, there were problems with the blower motors being bad. One sec and I will get you that fuse number. By chance do you own a multimeter or 12 volt test light? Thanks
Yes, that is the tell tale sign they ar going bad. Can you try testing the 2 wires at the blower motor plug connection for power and ground. Do not worry about polarity, I just would test it to see if it has power and ground.
I would start it because a control unit will prevent the HVAC from working sometims if the battery is just a lil low so start it please
Check the big 40 amp fuse, left fuse box for an open fuse.
Here is a screenshot I just made for you for this circuit. The large highlighted wire on the lower right goes to the fuse. You can see the ground is controlled by the "fan controller" or resistor
OK and the blower does not function when plugged in? If so, yes it has failed. Very common and you can get OEM cheapon Ebay compared to the dealer. Would you like the part number of the blower?
No, they go bad. You will probably see one go bad every 60,000-100,00 miles so not bad for a part that is spinning all the time!
Me too sorry for any typos, big fingers too
Is there anything else I can help you with today. Do youhave the owner's manual for your vehicle?
If you connected your test light to both of the wires at the regulator and got battery voltage (power and ground) then it is working. You could test it by reconnecting you test light or multimeter and adjusting the speed of the fan with the knob and see if the light dims or the voltage reduces as you reduce the fan speed.
Regulator must be connected
Well it was noisy to begin with,probably old and you disturbed the connection for the brushes to the motor. You might have done something but no worries, it was going to fail soon regardless. At least now you will have a good blower motor.

No,because the blower is dead. Unless you felt ambitious and tried to take the blower motor apart and clean the commutaor and brush area but it is probably not going to be successful and a waste of your time
What do you think? Are we OK now?
OK, please do not forget to rate my service please. The blower will fix your problem. The multimeter proved this when you tested it and the range was 12-9 volts. Thanks and stay warm! Frank
