Heater/AC Fan
How many settings does the fan have, 3? Low, medium & high? I recently bought my truck and it only blows on high, the last click down. The switch has 3 clicks down, but only high seems to work. How can I remedy this?

Sounds like your resistor on heater box under dash is bad or disconnected--3 wire connector--also check heater fuse as high speed on blower is on a inline fuse.

When my heater fuse blows (twice in the last week, goa short somewhere in the A.C. wiring, but can't leave the switch alone: I'm a dummy) it kills the hi setting on the fan too. I'd go after that resister. Just my Opinion.
