The blower on my A/C does not blow in the high position. The switch does not seem to be the issue, I have change it out. The blower fan adjust in the other two positions but does not work on high. Does anyone have any suggestions?

Thanks in advance.

Hi ashbyb, and welcome to the forum, on my C-3 there is a seperate in line fuse for the "High" fan position, I don't think you have one but if you look at the wireing diagram you may find a relay is not working properly. PG.

HI, the high speed fan relay is more than likely the problem. Don't know what year model you have but on my 85 the relay is located under the hood, passenger side near the blower motor.
