Question about 1989 Chevrolet Suburban
I have no heat coming from my heater, fan is on good and strong, I replaced the heater core, I have plenty of coolant level, no heat in defrost mode either. What's wrong?
If you haven't already, try replacing the thermostat located on your engine's intake at the upper radiator hose. If that doesn't work, it may be in the control pannel for your heat on your dashboard, causing the heat switcher in your air box not to switch. Also check the cable on the air box, as sometimes when you do a heater core the cable may not be exactly back in place, or it may have been bent.
Hope this helps
