The ac blower on my '97 Cheyenne truck only works on the highest setting. I have replaced the resistor once and the control module three times. Every time I have replaced the control module the problem was initially solved but then came back. What is causing this problem?

What does the connector look like on the back of the control head, make sure the pins in the connector are not burnt/melted, sounds like you may have a connection issue. Same goes for the resistor connector.
