Fan/blower speed not working at med/high setting

[Jeff65]

I tried this on my '65 two-speed fan motor switch and it failed although I have been successful at repairing switches like this in the past. Success depends on how badly the contacts have been pitted by past switch actions. Even if you are successful at repair you should look for a new one since expected life of a repaired switch is short.

Note that the switch for '66 has the same three positions and you might be able to adapt the '66 switch to your application. NAPA also has dozens of switches in their catalog with descriptions. Its possible you could find a suitable alternate switch.
