    2000 Volvo the front blower fan only works on three speeds. Changed the blower, resistor on top of it and nothing helped. What else can be checked?

    I don’t know about Volvo, but my international has a separate circuit breaker for high speed. Check there first

    I'll try swapping the switch, thanks, was putting it off, cause it looks like it's a pain in the butt

    The fan is on its way out.

    I've had this happen a few times and a new fan fixes it if the resister module didn't do the trick.

    Two question for you. Is the fan speed is the same on 3th and 4th position ? Do you have a manual control or automatic (with degree numbers) for heater operation ? Ben

    Update on this. The harness connector from the blower to the truck was bad.
