If you experience a vehicle with excessive A/C system pressures, did you know you could quickly rule out these easy checks before making any component replacements?
A/C Update: Risky Business
As you may know, the air conditioning compressors in many hybrid vehicles are operated by an electric motor instead of a drive belt. The motor’s insulated windings are immersed in the compressor’s lubricating oil. The oils used in these compressors are formulated to have high dielectric properties, that makes them non-conductive.
Tech Tip: Acura’s Battery is Dead, A/C Cools Poorly
If a 2007-2011 Acura MDX’s battery dies after the vehicle is parked for a short time or overnight, and/or the A/C system blows warm air, the A/C compressor clutch relay may be stuck closed. The A/C compressor may also be noisy and may be emitting refrigerant vapor from the relief valve.
