Ford transit mk 6 rwd 2.4 .... the blower motor recently stopped and after checking the resistor which was fine and the switch that on looking at had burnt out and melted the vacuum pipes that went into it. I have changed the switch but the blower motor only works in position 3. I don't want to keep running on this setting as I've been told it will burn the switch out.
Another thing is the blower motor in position 3 is not pumping out the air on full power
