Re: heater fan doesn't work on high setting

Figured it out. I installed a painless kit and painless heater a/c harness. I didn't realize the painless kit uses a ground and its own relay for the heater and apparently it only uses the relay on high and didn't have the ground connected. Once I hooked it up correctly everything works as it should
