Heater blowing Luke warm
Last winter when I got the truck 1988 k2500 I replaced the heater core and flushed and back flushed the system numerous times and the heat would stay lukewarm well winter came quick and still have the problem. I checked the heater core both inlet and outlet tubes to warm to touch. Truck does have ac but doesn’t work, seems like every actuator clicks while being used. Does anyone know how to diagnose the problem
