I have an 81 300D that has a blower motor that won't kick on for the a/c unless you tap it hard with the backside of a screwdriver or something else hard. It will work for awhile and cut out. I assume the motor is bad, and I have found motors online for under $70 but they don't come with the fan. I have tried for awhile to get the plastic fan free from the motor with no luck. Anyone have any solutions to removing the fan off that motor shaft? The only combo I could find online was over $250. I did find a motor combo cheap for the w126, but the housing that mates to the underdash is different. Does anyone know if the 126 is modifiable to work with the 123 as another solution? Thanks a bunch!
