Dang cheap German cars ! you'd think being in the land of cold & snow , they'd build a decent heater but Nooooooooo ~ after only 28 years and 281,000 miles , the brushes wore out and it stopped working =8-^ .
I ordered up new brushes from Kent Bergma @ Mercedes Source in Bellingham , Wa , removed it and began the fun ~ as this car had been completely filled with dense choking clouds of Diesel smoke (oops) , it was pretty nasty in there , I took some pictures of the cleaning and repairs , Tom was busy to - day so I didn't get pix of the important difficult bits but I will when we overhaul his fan motor , I have a lead on affordable brushes working now , IIRC Kent gets $9 , not bad but being able to get them locally would be nice .
Sadly the commutator on my motor's armature wore at an 4° angle and I thought it beyond salvage but it works just fine and the new brushes should wear in fairly soon .
Most of the work was the cleaning ~ whew ~ that took patience and diligence but was worth the effort ~ electrical devices don't like heat and dust covering everything is a dandy insulator .
The commutator end bushing is the self aligning typ ~ a very nice touch , I put three drops of oil on it but it may well be designed to run dry , I can't tell but it spins freer now .
