1994 Chevy Caprice Heat/ Ac blower speed control troubleshooting fan speed control went out and all i have is high speed on my AC. Now the high speed only turns on sometimes. (The Heat/AC fan setting. 1-Low, 2-Med/Low, 3-Med/High, and 4-High speed) All i have is High speed. But, Now the high speed option is off and on at times. ( acting up ) What is the problem here? Blower motor? Please help me figure this out.
