Why does my air conditioner/heater fan only work on High?
Our air/heater fan only blows air when it is set on high. It makes a hooting noise when it first starts like maybe there is something in the way. I have replaced the blower fan relay switch but that had no effect.
These were all excellent. I had to replace both the resistor pack and the blower fan motor. The video on youtube was great help also.
Thank you all.
