I need input guys! My heater was fine for 187k. Last week it was on high then stopped all of a sudden. Stays off for about ten minutes then comes back on. Always very hot. I took a shot and put in a new resistor. No luck, still shutting off, then coming back on. One interesting note, when I start truck heater blasts on high no problem. If I let sit in driveway, after about ten minutes blower quits. Once I get in and start driving for 5 minutes, blower kicks back on! When working I have all 4 speeds. Any ideas will be appreciated. Thank you all.
