heater fan only runs in 3thrd speed checked switch seems ok and checked res. seems ok the resistor blower make low speed, medium speed . check the resistor module
when the heater is shut off heat still blows out Some manufactures do not shut off fans there are on ata very low speed i do not know the reasoning behind this..
...low/med/high fan speed switch has a resistor in it that can also go bad, I changed that 1st, no change, swapped out that $6 relay and now I have a fan again :) Those are really the only 2 things ...
