I should have told you to test D with the key on AND the fan switch in the "almost" high position. This SHOULD give the same results as test C if the wiper contact in the fan switch is good. If the D test fails and the C test works the switch is bad.
With the ignition switch on connect your 12v battery wire to H, I, J and K one at a time noting results. I'm going to guess that all 4 will work as expected and that your problem is a bad contact on the wiper of the fan switch.

You were absolutely right on this one. I wired +12V directly to each wire and all ran the blower, lo-2-3.
Took the switch apart and it was corroded. Cleaned each terminal and also gave the whole console a good lube up and now buttons works smoothly again. Tomorrow going to test the switch, hopefully that solved the problem.
