My corvette is a 1974. Runs great. Just one recent issue. AC works on all speeds except high. This week, I replaced both the AC Blower Motor Resistor and the AC Hi Blower Motor Relay. Unfortunately, the AC still does not work on high. Any thoughts or ideas would be much appreciated. Thank you! Jeff.
Location of high speed fuse. Maybe this could help?
Not certain what you tested before you started replacing parts. Do you have power on the red wire at the high speed blower relay?
