Is there an easier way to test the blower fan motor?

[jbach36]

For the climate control blower motor, is there a way to TEST it (not replace it) without having to rip half the car apart to get to it?

Arthur Dalton said in his post "The test are made at the 3 wire connector behind the brake booster......Rd/Bk/Yl"

Maybe his is set up differently than mine; I don't see any obvious way of testing the blower motor behind my brake booster. Mine is a 1991 300d. To get to the blower motor on mine, I have to take off the entire windshield wiper assembly and other parts underneath that.

Thanks.
