Why does climate control only work on high speed?

There aren’t separate relays to mode control and the modes are switched by the climate control in the dashboard. If the fan is working only on high speed, it is probably a shorted blower motor resistor. The resistor is responsible for changing the voltage to the blower motor.

Why does my climate control go off at idle?

The system is probably low on Freon and when the car is at idle, there is no load on the system and it operates.

This switch turns off the compressor to prevent damage in the event of a low charge.
