Buick LaCrosse AC and Heater Controls
The Buick LaCrosse is a series of mid-size and full-size luxury cars introduced in 2004. If you are experiencing problems with the AC and heater controls in your Buick LaCrosse, then these replacement parts can help you fix it. With a wide selection of Buick Lacrosse AC and heater controls, you are sure to find something for your make and model.
How do the Buicks AC and heater controls work?The heater and air conditioner controls are designed to make your riding experience as comfortable as possible by carefully modulating the internal temperature of the cabin. The heater and AC consist of the climate control unit located on the dashboard, as well as the various doors and ducts that control the flow of air through the system. The particular climate controls present in the Buick LaCrosse will obviously vary based on the specific year and version of your vehicle, but in general, the LaCrosse series has a robust set of controls that let you choose between manual and automatic settings.
The automatic settings use the vehicles computer system to dynamically adjust the temperature controls. The 2017 version of the Buick LaCrosse has separate buttons for the fan speed, defrost, the drivers heated/vented seat, the passengers heated/vented seat, the rear window defog and heated outside mirrors, and a special temperature control and recirculation mode for the passengers. A separate climate button lets you control the temperature and climate settings from the touch screen display located on the dashboard. Older models may lack the touchscreen display or certain climate controls.
Why might you change a sedans control system?The symptoms of a defective or failing control system include poor air distribution from the HVAC or a cabin that feels too hot or too cold. A malfunctioning control panel is easy to diagnose because the buttons or knobs will stop responding to your inputs or only work part of the time.
What should you consider in the purchase of a new control panel?The most important factor to consider is the compatibility of the new control panel. Due to the nature of the temperature control system, most replacement parts are only designed to work with the recommended vehicle, so you need to check that the new control panel is compatible with the make, model, and year of your particular vehicle. There are generally two options: either purchase a refurbished part that comes directly from the same type of compatible vehicle, or buy a new part directly from the original equipment manufacturer, or OEM for short. Another factor to consider is that on some models of the Buick LaCrosse, the temperature control panel is integrated directly into the navigation and audio controls, which means the heater controls may be included in the control panel as a unit and need replacing at the same time.
