Why is my climate control not working?

This could be a fault in the refrigeration circuit (bad compressor, plugged orifice valve, blown fuse or bad relay, low refrigerant or no refrigerant in system), or it could be a bad BLEND AIR door control motor inside the HVAC unit that is not routing the air through the A/C evaporator.

Is there a fuse for climate control?

Typically, AC systems use “TR”-type fuses to ensure safe system operation. However, if you’re in a pinch and need to replace a fuse quickly, you can use a fuse rated for a lower amperage than what the system is rated.

What does the heater control switch do?

The heater control valve allows the flow of coolant through the heater core to be controlled and switched on and off without affecting the operation of the rest of the cooling system. It may be located on the inlet or the outlet port of the heater core and activated by a cable, electronic control, or a vacuum signal.
