1990 Buick Regal Air Conditioning Parts

Our products are engineered and tested to provide years of trouble free operation. Backed by over 50 years of mobile a/c experience, fix it once and fix it right with Carquest.

Modern vehicles may have 100 or more electrical harness connectors in every operating system of the vehicle. Terminal tension may weaken with time or corrosion may occur within the connector housing making replacement necessary. When replacing any harness-connector assembly approved wire termination methods must be followed to ensure a successful and long-term solution to the original problem is made. A failed terminal connection, terminal corrosion or damaged wire will result in an electrical system fault.

Carquest Expansion Valves are designed to regulate the flow of refrigerant through the air conditioning system to provide optimal cooling to the passenger compartment. Each expansion valve is manufactured to original equipment specifications to perform its function even in the harshest climates. Each part is supplied with the necessary gaskets and o-rings for installation.

The Carquest Premium line of vehicle electronics are designed for OE form, fit and function for both import and domestic vehicles. The A/C Pressure Switch monitors system pressures, aiding in proper and efficient control of the compressor, fans and system levels. An improperly functioning A/C Pressure Switch will provide erratic or inaccurate actuation and operation, severely affecting system performance and function. Without reliable and accurate actuation from a properly functioning A/C Pressure Switch, critical components and the system as a whole are left unregulated and unprotected which can lead to excessive wear and tear on critical components and costly system damage.

Carquest A/C Accessories provide a comprehensive offering of premium quality fittings and tools to service all aspects of an a/c service from the most simple fitting replacement to complex diagnostics required for late model applications.

Carquest New Compressors are designed, manufactured and tested to meet or exceed strict original equipment specifications for superior quality and performance.

GM Genuine Parts A/C Orifice Tubes are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These tubes, which separate the high and low pressure sides of the air conditioning system, control the flow of low pressure liquid refrigerant into the evaporator. The orifice tube is essentially a calibrated restriction located at the inlet to the evaporator. This causes the necessary pressure drop to allow the liquid refrigerant to evaporate within the evaporator and absorb heat. Since the orifice tube is fixed, the system is regulated by either cycling the compressor clutch or by a variable displacement compressor.
