heater fan speed
Hey Everybody. (as Dr. Nick would say)
Got a question.
I have a bit of an issue with my heater fan.
The story so far......
The fan stopped working. Even with the quick defrost button.
I took out the relay for the fan and the "on - hot" lead was melted.
A little shocking to say the least. The relay is fine but when I took
out the fuse panel, a wire had been bared and was shorting out to the
frame. It looks like the wire was to the a/c. I wrapped up the wire
again and made sure that this would not happen again. I cleaned the
contact on the fan relay and put it all back together.
I now have the fan working but only on the high speed setting. The
quick defrost works now too. At least I have some heat and a defrost.
Does anybody know how I can get the slower speeds working.
Thanks in advance
Tod

heater fan speed
it's quite likely oxides in the "central eletronics", although it may also
be worth checking that the short didn't destroy the dropping resistors that
are put in series with the motor when you select lower speeds - can't
remember where they are physically, but that's a second possibility

heater fan speed
oxides in the "central eletronics" ?
I am not familiar with this.
Where / what is it?

heater fan speed
the "central electronics" box (that's what Porsche calls it) uses copper bus
bars, and on my car they oxidized and caused some odd problems, one of them
related to the fan. "central eletronics" refers to the box above the pedals
that has all the fuses and relays in it.

Ahhh. Looks like I will be taking out all the fuses and relays again.
Good thing I kept my diagram.
Thanks
