the regulator and one blower motor went out on my 964. the other is near death according the service shop.

ballpark.. what should it run to replace both and the regulator ?? labor hours ?

quick interweb search shows $208 for the regulator and $763 for the blower motors (assuming i found the correct parts)

I don't know much about the regulator, but the a/c fans are very expensive. $750-1000 each from what I have seen. A shop with knowledge of 964's should be able to change out the fans in about 4 Hr +or- have you thought of getting the old once reconditioned, lots of info here on RL.

People have found replacement motors (Mercedes I believe) and adapted them to the existing squirrel cage fan blades....

My searches seem to find the engine blower motor...?

I need something plug in ready as I am not going to do the work myself so any sort of Mercedes retrofit might not work.

Vertex has them for $749, Pelican Part $978. You can also try Sunset Porsche in Beaverton Oregon, or give DC Auto a try, they carry a lot of used parts.

The part numbers are as follows.

964. 572. 015. 01 left side
964. 572. 016. 01 right side

The previous owner of my car had them done right before i bought the car... $3000 total for the job..ouch!

What Streetdaddy said.... I had mine done this summer and with parts and labor it was about $2500. Hurt. But they work now.

What is it on the blower motor that goes bad? is it the squirrel cage that breaks up? motor bearings?
Since brushes can be changed.

crg53

It's the bearings that dry out. They are sintered bronze bushings (oil lite) which are porous and hold oil. Over time they dry out and glaze over, then start making noise, and if left with out reoiling, will wear out.

aha so the first sympotms are squeeling then?
Is it possible to change them or is the motor stamped together? I can machine new in the same material.
If not it must be possible to use a stock 12v motor and make and adapter cheaper than buying new fans.

You relubrictate the old ones, I did on mine, they have been good for 4 years now. Take the fans/motors out. Stand on end, take off the washer and felt, put a drop of 30w motor oil on the shaft, let it soak in, then repeat until saturated, assemble, then do the fan side bearing. Will take a couple of days, but well worth the trouble.
