Heater blows.....but not heat??
89 Chevy 1/2 ton. My heater blows...(pun intended) it will blow, change from defrost to panel, but it blows lukewarm at most???? Heater core was replaced about 2 years ago. Running a 185 thermostat? Radiator full. WHat can it be? It didnt work too well last year either come to think of it. I put in a CD player about 3 years ago, could I have knocked something lose?????
It is warm in TX, but gets kinda cold at night these days.
