Pontiac car parts for air conditioning systems are like the components in most auto A/C systems. The specific brand name, size and strength of each component varies, but essentially, the system boils down to the same thing. Each A/C system has a compressor, a condenser and an evaporator. Some have an accumulator/drier. Some just have a drier. Some models, like the Sunfire, use an orifice tube as the regulator that determines how much coolant is pumped into the evaporator. Other models use thermal expansion or block valves to do the same job.

Where to Find Pontiac Car Parts for the A/C System

Both new and used A/C compressors are available online and in retail outlets for the Pontiac air conditioning system. Whether it's best to buy new or rebuilt is difficult to judge. Rebuilt parts cost considerably less than new. Some people prefer to buy new, though, to ensure that the part will be in good working order when it arrives. Regardless of whether the compressor is used or new, it should come with a warranty. Never buy car components that do not have some sort of warranty protection or a good return policy.

For classic Pontiacs and other brands that were popular decades ago, like the Plymouth, the best place to find parts is a junkyard or a business that gets its stock in a similar fashion. Some car restorers will buy entire autos for the components.
