anyone know what part number or have a picture of what type of fuse the rear blower uses? I had my jumpered as the PO removed the blower. Is it a "generic" 4 blade relay?
The other day I heard an awful chain saw like noise from the rear and isolated it to the blower motor. Thanks to this thread I have everything apart already but I’m trying to figure out how to separate the motor and the squirrel cage fan from each other? I don’t see anything hold them together, is this a press fit that needs to be pried apart?
Also a heads up, Amazon has the motor available for $158 for anyone looking.
I just got the same issue recently and got a quote of $750 from my garage so decided to "do it myself".
1) I purchased the Bosch motor (original Porsche motor) at FCP Euro for $108 (www.fcpeuro.com).
2) Pulled everything apart (easy process)
3) Then faced the same challenge as to remove the fan from the motor. This is the most tricky part because the fan can break easily and you won't be able to purchase it separately... FYI Nothing holds them together. The easiest way is to buy a "puller" to avoid breaking the fan. What I did is to spray W-40 where the fan and motor meets, then set the fan above 2 pieces of wood with the motor hanging under. I used a "punch" tool and hammered the motor out. It was a bit hard at first but then it worked. Some people advise to put it in hot water to dilute the plastic but i didn't have to do this.
4) A good cleaning and put it all back together.
A hammer, a punch and 2 pieces of 2"X 4". When you put it back together make sure the fan has clearance in the housing, I had to adjust mine after my first fitting because the fan was rubbing on the housing. .
Aye, wooden blocks and some careful drift tapping of the motor shaft. First sign of a completely knackered bearing was the fan rubbing and shrieking. Brand new Bosch motor £80 at the time I think. Pic below of how bad mine became - massive wear on the motor casing indicated.
My motor doesn't look that bad at all, my evidence came from bits of dust on the dash at first which I thought was insulation. Not long after the dust came the chainsaw noise and once I had everything apart I could see where the fan made contact with the housing. I'm taking advantage and cleaning up the engine bay while I wait for the motor to arrive.
