An Oldsmobile Calais HVAC Pressure Switch protects the A/C loop by shutting off power whenever the pressure is outside the acceptable range. This prevents damage to the compressor, which can be very costly. Engineered to exact factory specifications, this HVAC Pressure Switch allows every Oldsmobile Calais from the early base cars to later International Series models to heat and cool correctly, just like the original. It threads into the high side port to read the pressure at the current time. It then signals the climate computer to cycle the compressor only when the time is right to save energy and prolong the life of the part. Due to the HVAC Pressure Switch's millisecond reaction, cabin temperature remains steady during traffic pauses, preventing distracting and dangerous heat spikes. According to drivers, this little part is a boon to fuel efficiency because the compressor is never operating longer than necessary, while its fail-safe cutout prevents fragile lines from bursting. In later years, sensor fusion was added that allowed the HVAC Pressure Switch to work in conjunction with humidity and ambient inputs, giving any Oldsmobile Calais smoother automatic climate control. The switch's tough diaphragm resists vibration from rough pavement, and this feature has made it a favorite with long-term Oldsmobile enthusiasts who expect parts to last. With calibrating every cycle, the electrical load is kept in balance, thus improving overall performance further in a Calais. The factory's O-ring and simple hand tools are the only materials needed to change your HVAC Pressure Switch. A quick pre-summer swap delivers visible airflow confidence. The HVAC Pressure Switch is compatible for use on 1985 through 1991 Oldsmobile Calais sedans and coupes, meaning it fits first generation badges and later Cutlass naming years equally well. The HVAC Pressure Switch preserves the compressor, trims belt strain, and gives each Oldsmobile Calais driver the opportunity to focus on the road by constantly checking line pressure. Due to these concrete benefits, the HVAC Pressure Switch is impressive climate technology.
