Last summer i replaced the resistor pack on the fan motor for the heat. Everything it tight and works. Periodically the fan will stop turning even when the swithc put on high. this is on a auto climate control system in the tblazer. the control head module has to be turned off then back on and the fan works again, sometimes the fuse has to be pulled. any one think this is a control head issue or just coicidence turning it off works and is something else? :bonk:
