Heres the issue I got with my heater and i'm hoping someone on here might know what the problem might be before I start spending money.
Its on my 73 F250 cc, when I put the fan speed control in low or low/medium the fan will work just fine. But when I put the fan speed control in medium/high or high the fan will run for about a minute and then it shuts off then I have to turn the heater off and wait about an hour then I can turn it back on to low or low/medium. It sounds like something is getting to hot thats why its shutting itself off. Can it be the heater control relay right under the dash or could it have something to do with the blower motor. I sure dont feel like pulling all that crap out but if I have to then I will. Just hoping maybe someone on here might have had this kind of problem before.
