1977 Mercedes-Benz SL-Class - climate control blower switch

climate control blower switch

I’m guessing either faulty switch, or faulty blower resistor. Is it only the low speed that’s not working? If so, blower resistor is probably the problem.

Low speeds 1 and 2 are fine, but it loses detent and it’s nigh impossible to get speeds 3 and 4 to lock.

Seems more like a faulty switch then. The best solution? Ask your shop to verify the switch is bad, then replace the switch.
