I while back I posted a problem with my 850 where the blower motor on the climate control system would cut out under certain conditions:

1) When fan speed selector is set to Auto and ECC ramps up speed to max setting to cool/heat interior of car.

2) When quickly moving speed selector to max manually.

Under these two circumstances, the blower would speed up and cut out before hitting the max speed or shortly after hitting max speed. I know a few others have verified having this exact problem.

Initially, I thought it was the relay and since it was only $20, I ordered one and replaced it. Unfortunately, it didn't fix the problem and so I made the plunge and order a brand new blower motor from Trollhattan for $150. I decided against buying one from a wrecking yard ($60) because I intend on keeping my brick and didn't want to repeat the work in a couple of years. To make a long story short, the new blower did the trick and the ECC works like it should.

The job isn't difficult and just a little time consuming. Having removed the blower once before, it took me a little over an hour to finish the job the second time around. If you plan to tackling this repair, I have a couple of suggestions.

You will need torx drivers, T25 I believe, 3/8" socket with a 3" or 5" extension, phillips and regular screwdriver. If you have a Haynes manual it gives you a general guide, but leave out some details. After removing the lower plastic cladding and steel knee bolster, you will have to remove the glove box. There are two curved, plastic arms that act as detents on either side holding up the glove box door when open. You will have to remove these to take out the glove box. According to Haynes, you can use a small, flat screwdriver to release the arms from the door. I found it much easier to do this from the other side; however, that requires removing the door cover from the cup holder frame. Just remove all the phillip screws and it should come right off. The two screws near the hinges are the hardest to get at. You can use an screwdriver with a 90 degree elbow or a phillips bit with small combination wrench to turn it. There will be a lot of plugs and connectors on the blower, you can remove all of the them without having to disconnect wires. Unplug the connector to the blower and remove the 4 screws. You'll have to move the wires around a little bit and with a little wiggling you should be able to remove the blower. Reverse the process and enjoy your new blower!
