300E heater blower

[robi99]

My climate control blower has been making intermittent noises for quite some time. It's getting worse. I have searched this forum and concluded that I should replace it and not try to lubricate the bearings despite the success of some folks with some models. What I was not able to conclude is whether this is a DIY job. Some posts indicate 'Yes' and others say to have the job done by a dealer or reputable shop. I don't want to beat a dead horse but I would like to save the 4 hours labor if this is reasonable. Can I have some feesback on the DIY question. Car is a 1989 with 105K miles. Also, should I replace the blower controller at same time or is it part of the blower assembly??
Thanks...

The blower motor replacement is an advanced repair. You should only attempt it if you have a good grasp of mechanical knowledge and alot of time on a saturday.
I would suspect that it might take you at least 3 hours.

Our shop charges 2-2.5 hours for this job I think. I don't know where 4 came from.

You should not have to replace the controller at the same time.

I am a DIY-er. If you have the CD/manuals, have some mechanical abilities and ENJOY working on your car. Yes, you can do it. Otherwise, go with Benzmac and pay the 2.5 hours, it is worth it. It will take you much more than 2.5 hours.
