Question about 1989 Chevrolet Suburban
I have a 454 93' Suburban and no heat. I replaced the heater core, have plenty of coolant level, the fan blows good and strong. The thermostate reading is normal. Why is there no heat coming through the heat and defrost system?
There is a valve that allows heated water to flow through the heater core when you select heat on your controls. This valve should be located under the hood and one of your heater hoses should run to it. Your valve is stuck or failed for some reason. Check it out.
