Where is the resistor on a Buick climate control?
If it is shorted, the voltage passes straight to the blower motor causing only high speed. The resistor can be found next to the blower motor below the right side dash near the glove-box.
How does the condenser work in a climate control system?
• The condenser transfers heat to the outside air and condenses the refrigerant to a liquid. • The receiver drier (liquid tank) filters the refrigerant and stores any excess liquid.
How does a climate control system work on a car?
For example, when a customer selects Defrost, the system opens the fresh air intake door, activates the heater core and refrigerant loop, directs air over the evaporator and the heater core, and blows this warm, dry air through the defroster ducts on the dashboard.
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.

What to do if your climate control is not working?
Instead a communication wire passes through all modules informing the HVAC module how the lights should be operated. However, since the problem exists only with the HVAC, it is the component to blame. The solution is to replace the HVAC control module since the lights are internal and cannot be replaced.
Why does the AC blow cold air on the driver side?
Crank the vehicle without touching the climate control panel for one minute. After this try using the AC to check if it blows cold air on the driver’s side. If it is operating properly, the problem is with the actuators. If it is not working, the climate control panel is faulty. What could be causing climate control problems on the Buick?
