Heater switch problems
I am putting the interior back in my 76 and ran into an issue with the heater/ac switch. Hopefully someone out there can help me on this one. When the fan control switch is in the off position it is running the blower in what appears to be low speed. As I turn up the blower speed the blower does increase to the next level until I get to the high position. When it is in high it turns off. Has anyone experienced this and if so what is going on? Thanks for your help in advance

The blower does run on low speed with switch off due to the Astro-Ventilation design. Your high speed may not be working because the high speed blower fuse has blown. It is a 30 amp in-line BUSS fuse located around/under the brake master cylinder.
