Your Chevrolet Suburban air conditioner must be cleaned and the filter replaced at least annually. Qualified service technicians are certified by the Mobile Air Conditioning Society. A bad interior temperature regulator, sensor or control module requires dealer service and special tools to repair the complex automatic climate control. Dealer service ensures reliability, dealer parts and a warranty. Your air conditioner must be lubricated because your condenser can cause your engine to overheat.
An air conditioner compressor runs hot and pumps refrigerant through your air conditioning system. The compressor must be adequately lubricated with oil designed for Chevrolet Suburban air conditioners. The compressor will not work if the refrigerant is low or contaminated. Bad relays, fuses, wiring or switches, or a faulty control module can cause your compressor to malfunction. The air conditioner compressor with a one-year warranty has a natural finish, four-groove belt and clutch. The compressor bearing is 1.573-inch interior diameter and 2.441-inch exterior diameter, and is sealed on both sides.
If the condenser is dirty, flushing the compressor moves sludge through the system. The condenser collects filth and oil out of the refrigerant from the compressor through the expansion valve. Sludge can block the expansion valve. If oil cannot flow through the condenser, the compressor does not receive oil, lacks lubrication and overheats. Parallel flow air conditioners are difficult to flush because many tubes are attached to them. Parallel flow air conditioners are difficult to flush because many tubes are attached to them. The condenser with a one-year warranty is the parallel type; it has an aluminum body without rear air.
An inoperative blower motor and fan will cause the compressor to disengage. If the fans do not operate properly, the compressor may overheat and fail, causing your car's engine to run hot or overheat. The main cooling fan is near the radiator and the main hose runs from the radiator to the passenger compartment. Diagnostic code P0480 indicates that the main cooling fan failed, and diagnostic code P0481 means the secondary cooling fan failed.
The cooling fan draws air from the engine compartment through the radiator and air conditioning condenser. The vented blower motor for the Chevrolet Suburban is 3.25 inches in diameter and 4.31 inches in length, with a shaft that is 1.31 inches long and 1.31 inches in diameter; it requires 12 volts of power. The motor rotates clockwise with the wheel and has one terminal.
