Replaced my heater fan motor today on my 88 735i. Working outside with temp in the 40's with my physical limitations increased my time to do it. I had received up a good used one blower unit from www.vinesbmw.com Friday and weather was sunny. My blower was making a lot of noise expecially in temp below 20 degree. My brushes were gone. The lead to each brush was nearly touching the armature. The used one a good length of brushes left with no end play. I am glad the job is done.
Remove the overflow tank on the firewall and then the panel it bolts to and your are into the fan compartment. The unit is behind a thin piece of plastic that attached by two peices of double sided tape. The locatation was tight but doable for me. I do not expect there will be a next time but if it was I could do it in 1 hour. If you have a good shop that can do the labor for $40-60 I would say go for it. With everything plastic it is easy to break more that you fix if, especially in the cold. Forget oiling it because labor is the same so you should just get a good used/new unit and replace it while you are there. I also replaced my 82 733i blow when it had 150K miles for the same reason several years ago. Since they run all the time they just wear out. Best of luck.
: I have a 1988 735 iL with a squeeky heater fan also .Is the fan accessible for a lubricant spay. Also I have no heat from the driver uper vents but heat from the foot area. Thanks for the help
