Blower switch or motor?

[tgreen]

AC/Heater blower motor only runs on high switch setting. Is it the switch or blower motor?

sound like your resistor is bad (fits in the blower housing) since it is not used on the high setting (full current) Had the same problem on my Contour a few years back.

Yep, sounds like the resistor that bolts into the blower case, near the firewall.
