About a month ago, the heater blower in my '87 560SEL stopped working although all other functions of the climate control system appear to be working fine. Given the current cold weather and the more frequent need for defrost, this is not something I can go without for very long.

From reviewing posts here and the FSM, it appear that there are three possible problems: bad blower, bad contacts at the switches/buttons, or the blower control module. Is one of these generally more common than the others?

Thanks
