long time boys my 1998 blazer is doing wonderfull glad we could fix that one but now i have another problem and another suv its a 1997 gmc jimmy it has no heat at all no hot no cold nothing blowing no response from the climate control either i am going to assume that this would be a problem with the blower motor or climate control but i am not sure where to start looking it does warm up but nothing blazing hot both cords coming out of the heater core are hot and the same temp. checked the fuses inside the truck none are blown
