'82 240D Blower Motor
The car in question is a 1982 240D manual (upgraded w/ a 300DT engine)
1. I have a short somewhere which prevents the blower motor from consistently running. a. its not the fuse. I can manipulate the fuse all I want but it neither gets it going (when down) or turns it off (when working) b. its not the wires around the motor itself c. THE STRANGE PART: is that the most effective way to get the blower to turn on when its not functioning, is to open and slam the driver's door. d. reaching under the driver's footwell and moving wires does nothing either 2. The fan knob will only turn to position #2. If I force it, I can gain position #3 just short of breaking it, but it won't stay there. any ideas? Thanks Don

Given any consideration to the blower motor brushes?
They eventually wear down and start getting intermittant. A search here should provide plenty of information. There are new brush kits available. Ken300D

Thank you both.
I hadn't thought about the brushes shorting out. As for the fuses, I've tried 3 different new ones so I know the problem lies elsewhere. Appreciate it. Don

Brushless
dieseldon and all,
The newer blower motors have the brushes exposed so that they can be replaced without disassemblying the motor. The only difficulty in replacing any of the brushes is obtaining the brushes or making new ones, plus soldering out old and in the new ones/ . Any injection mold making shop will have scraps of carbon electrode material, which they'll probably give you for free and it can be used to make new brushes which if made correctly can be installed easier than the original ones. I made two sets recently this way and installed in both the new motor and the older sealed unit. I just drilled and tapped the outer end of the fabricated brush and then drilled another hole in the side so the wire could be inserted and a set screw tightened down with a little Locktite for good luck. Both worked fine! To get the original remmant off, I merely crushed it exposing the wire end. BTW, the carbon material can be easily fashioned into shape with 180 grit sandpaper. On the other hand, if you don't always have to pretend you're on a dessert island you can order the brush set and the workbook describing how to do the job from, www.**************.com. He has a great booklet on vaccum systems too. Check my website for a great Christmas gift for the hobbyist! Good luck! Ben www.reproduce100s.com
