Default Heater Fan Motor

I posted a similar post 3-4 weeks ago and did not get the help that I needed. My heater fan only comes "on" when I go over a bump in the road. I just had my Climate Control repaired due to missing pixels and I thought that this might solve the problem, but it did not. When the heater fan does come "on", ALL fan speeds do work and everything is fine and I I get great heat. Another Saab owner that I talked with stated that there is probably a "short" or a loose wire at the blower fan motor. Could this be the problem and an easy fix? I would appreciate any thoughts.

You need to remove the blower motor and replace the brushes (or have it rebuilt).

It's a pretty easy do it yourself.

Yep, I just did mine and it fixed everything. The symptoms leading up to it were the same. In fact, it doesn't just have to be a bump in the road, you can just hit areas in the dash and it will come on. But unfortunately it will eventually not come on so you should pull the fan out and replace it or fix the bushing. If you replace it, the part is around 150$. The bushing repair (I've read) is an easy fix and does the job 95% of the time. Good luck! If you run into any issues pulling it out, let us know. My only suggestion is to take your time when pulling the plastic under the wipers off and follow the instructions because the plastic caps underneath are VERY easy to break (still not a huge deal if you do break one...I did). Also, I also recommend removing the wiper mount located above the wiper blade for the extra room. Lastly, wear some leather gloves as the plastic is a bit sharp for bare hands.

i did mine today. it to the stage where it didn`t work at all. not good when the last week has been cold and frosty. took plastic covers off and wiper motor and linkage. undid the fan, but could not pull it out due to the gap been to small.
so i got it postioned at a angle, then replaced the bushes with it still in the car. a bit fiddly, but all good and working now

Seems those motors ONLY last 10 years (cheap crappy Saab parts ) as my 2001 wagon is doing exactly the same thing.

I have to say that these are the best fan motors of any vehicle I've owned - they stay nice and quiet and work well for 10 years! The worst was the Mercury Sable - new motor every other year.
