My heater fan stopped working, had been intermittent for last year. Today stopped working on any position. I took the fan motor out to test, hooked up to battery and fan runs full speed fine. So I have to assume the 4 position switch is the problem. Some sites refer to a fan relay, there does not seem to be a relay under the hood drivers side. Help with diagnosing.
