A/C - Fan Problem - Any Ideas?

I'm having problems with my '74 K20 4x4, specifically related to the air conditioning. In any other switch position other than A/C my fan will operate at all speeds but when switched to A/C the fan will only operate at one speed. Anyone else experienced this? Your suggestions would be appreciated.

Re: A/C - Fan Problem - Any Ideas?

I had the same thing probably 8years ago, There are TWO fuses for the a/c!
One of them is for the speeds above low (weird uh?)
bad news is I don't remember if it was in the fuse box, or behind the dash, inline on the wire leading to the control switch, or an inline under the hood ??? look for it in the order I listed them. Sorry I can't tell you exactly were it is at but at least I can tell you what to look for!

My '78 1 ton farm truck does that too. I just haven't taken the time to look for the problem.... (or the fuse...)

Let me know if you find what the problem was...
