  1. Heater fan problem

    C3 Tech & Performance
    My fan will not run on 1st 3 speeds. I have 12V to both sides of the fuse. I know the high speed relay powers the 4th speed and it runs there, so I don't think it's a ground issue. It ran a couple of days ago and quit. I found the fuse blown and replaced it, but now won't run. Where do I start?
