AC not blowing on low but blows on high???

[Ralph50]

Searched forums but couldn't find a direct answer?

I'm assuming its a relay somewhere?

Can someone point me in the right direction?

Thanks

Sounds like a blower motor resistor failed, should be in the air duct just downstream from the blower motor

Thanks. Never heard of that though. Gotta check the manual.

Forget the manual. Anyone with the same problem go here:
