964 Rear Blower Motor Replacement

Hello All. Thought I might share a recent 'success' when my rear blower motor failed, shorted to earth and zero heat, air flow into the cabin.

Main issue was sourcing a new Bosch motor. It's well embedded into various plastic components and not available from Porsche - though they'll supply a complete assembly. A snip at around £640. The motor on it's own took some finding and, from Parts in Motion, was a very reasonable £94 delivered. Part number 0130 111 145. Replacement was a case of carefully taking the old one out of its housing, prizeing the fan off the shaft and switching everything over.

Here's some pics...

Well done :thumbs:

Always great when one can make a £546 saving....
 
The problem is getting the fan off in one piece ..

method that works for me .. well some of the time .. get someone to hold the fan .. you then beat the shaft with a hammer / punch .. they complain a lot but ignore them !

i did x4 air blower fans from a 993 not long ago ( spares ) .. got x2 off this way . others fell apart .
 
Whatever works, works! I locked the old motor in a vice and gently eased the fan off with a pair of screwdrivers, opposite each other. At the start I didn't know how it was fixed on...once it started moving the rest was straightforward. Used a heat gun too, just to warm things up a bit. That helped.

Knowing the full cost of the 'assembly' it was very satisfying to track down a new motor, get it fitted successfully...new fuse and away it went. Nice clear windscreen again and for about 20% of the cost otherwise.
