Moderate Your Cabin Temperature With Quality A/C and Heater Controls

It’s frustrating on a drive when you attempt to adjust the temperature, blower fan speed, or vent selection, and nothing happens. Now you are stuck sweltering or shivering because you can’t adjust your climate control system due to faulty A/C and heater controls.

Most modern climate control systems have three main controls: temperature control, blower speed control, and vent selection. Behind these are various switches, including the temperature control switch, fan speed switch, and vent-control switch. These are the main A/C and heater controls that feed electrical current or vacuum – some older vehicles use mechanical arms and cables instead – to the various parts of your climate control system to get the response you want.

When this interface fails, you’re often stuck with no A/C or heat or the last setting before it failed. Fortunately, you can get everything back to operating condition with replacement A/C and heater controls, whether it's simple temperature control knobs, the control switches themselves, or other components, such as a blower motor resistor.

Get High-Quality Replacement A/C and Heater Controls

When it’s time to fix your faulty climate control system with new A/C and heater controls, not just any old part will do. Ensure everything operates as intended with high-quality A/C and heater controls.
