655-00781 PONTIAC Heater Temperature Control Ac Rear Defrost

Review PONTIAC Heater Temperature Control Ac Rear Defrost Fits 88-91 Am for GRAND

The Pontiac 655-00781 is a heater temperature control and A/C rear defrost assembly specifically designed for Pontiac vehicles from the 1988 to 1991 model years. This assembly is an essential component of your climate control system, allowing you to maintain optimal temperature and defrosting capabilities in your vehicle's rear cabin area during harsh winter conditions.

The heater temperature control part of this assembly is responsible for regulating the temperature of the air that flows through the heater core and into the rear compartment of your vehicle. It consists of a temperature control valve, which allows you to select your desired heated temperature via a knob or switch. As you turn the control, a diaphragm connected to the temperature sensor moves, opening or closing an internal passage in the valve. This, in turn, changes the flow and mixture of hot air and coolant, keeping the temperature inside your vehicle comfortable.

Meanwhile, the A/C rear defrost function plays a key role in melting ice and frost from the back windshield and rear windows. During cold weather, enabling the A/C mode and securing the blower fan in the high setting can activate the defrost cycle. Cold outside air is drawn into the vehicle's evaporator core and cooled via the refrigerant to create cooling effect. This chilled air then circulates through the heater core to be distributed to the rear compartment, de-icing the windows and improving visibility.

Integrating both heating and cooling capabilities, this 655-00781 assembly ensures a year-round comfortable cabin environment. It is a crucial replacement when previous components malfunction, causing issues with the climate control or defrost function in the back seat of your Pontiac vehicle. Make sure to maintain proper operation of your climate control system to keep you and your passengers comfortable and safe on the road.
