A/C & Heater Controls for Jaguar S-Type

Jaguar S-Type A/C & Heater Controls

Like any other frequently used component, the A/C and heater controls on your Jaguar S-Type experience wear over time. When the climate-control system fails or starts to behave erratically, it’s a sign that you may need a replacement control in front of or behind the dash. Whether you’re replacing a cracked climate-control panel or dealing with a malfunctioning temperature sensor, this selection of replacement parts can get your cars heating system back to normal.

All S-Type models were manufactured with a digital climate-control panel; all settings are displayed on a digital screen in the center of the panel. While the specific layout and button options vary, common controls include the following:

• Temperature - OEM control panels for the S-Type use up and down buttons to select the temperature, which is displayed numerically on the screen. Later models offer two temperature-selector sets as part of the dual climate control system.
• Fan - This control adjusts the blower speed. Many S-Type panels use a knob to control the speed; a push of the knob turns the fan on or off.
• Fahrenheit/Celsius - This button changes the temperature display units from Fahrenheit to Celsius.
• Mode - These buttons control various modes, including vent configuration, A/C on/off, automatic climate control, and front and rear defrost.
• Recirculation - This control closes the exterior air vents to block outside air and circulate interior air for faster heating or cooling.

The heater control valve is a key part of the climate control system on your Jaguar. It manages the coolant fluid that passes through the heater core, enabling the system to achieve your temperature selection. This valve allows you to turn the heating or A/C system on or off without having an impact on the cooling of the rest of the engine. When your car stops producing heat or when the heating and A/C system don’t respond to your chosen settings, it can be a sign that the valve is broken.

The sunload sensor detects the amount of sunlight that comes into the cabin of your Jaguar. The sensor then sends that information to the climate-control system, which adjusts accordingly to keep the cabin at your chosen temperature. In most cases, the sunload sensor is mounted on the dashboard of your vehicle. When the sensor is malfunctioning, you might notice that the interior of your Jaguar is warmer than the temperature setting.

The Jaguar S-Type was in production from 1999 to 2008, and the car went through several redesigns during its lifetime. To ensure you get a compatible part for your Jaguar, go through these steps:

• Select a part - Choose from HVAC control panels, water valves, heater control valves, air temperature sensors, and more.
• Pick a type - Both OEM and aftermarket parts are available.
• Check the year and specs - Verify that the part is compatible with your vehicle’s year and specifications. Earlier and later models have different heating and A/C components.
• Match your interior - If you are purchasing a control panel or an individual knob, check to make sure the color and style matches your Jaguar.
