I am having an issue with my 1999 GMC Yukon Slt 4x4.
The heater controls that change from defrost to feet isn't working. The actuators have been replaced and the the climate controls have been replaced. Also, the A/C button doesn't light up. Mechanic doesn't know. He said if it was a year older or a year newer he could narrow it down.
Also, I am getting hardly any heat coming out. Maybe around 70degrees in the interior at normal operating temp. Radiator, water pump, heater core, thermostat, all hoses and heater blower motor has been replaced. No leaks anywhere. Only thing I can think is the heater control valve, but I am growing tired of throwing money at this thing. I would greatly appreciate and leads to what these issues are and a solution on fixing them.
