that was very well presented, good work. I have a 1990 300TE and the blower is heading south and I hate doing blower motors, just finished one on a 1988 BMW 325iC and then this darn one starts up. I looked my car briefly but now I have much more insite. thanks.....btw..and all of a sudden it hit me, I have wondered why 1 big wiper instead of 2 smaller ones.....no linkage between wiper arms...bigger motor. less moving parts; makes sense i guess....interesting concept
