Question about 1997 Buick Park Avenue
Car shop yesterday says I need a new compressor, BUT over the past 6 months, National Tire & Battery just recharged it with freon and it worked fine(ice cold) until now. Is there really a potential compressor leak OR something else?? Otherwise, cost $650 to $800 repair cost. Heater works fine!
IF you had the system re-gassed and it worked fine for a while then there is a leak in the system. Leaks occur at the compressor seal behind the pulley ( repairable ) in pipes and fittings and in the evaporator and condenser ( corrosion holes from acidic process when there is moisture in the system from running without gas.) Unfortunately the only fix for this is new parts . There is a uv light and yellow coloured glasses that show up the leaks as a green dye, so have this done first to determine the degree of cost before you commit

The battery change and the problem, may coindental or maybe not, your air regulator door actuator is probably stripped our just worn out, the regulator is attached to the damper that controls the drivers side air over the two coils. shouldn't be to hard to locate, but will require laying on your back and removing the under dash panel. it will probably be a small rectangular shaped module mount to the duct at a damper door! i hope this helps, if you want exact instructions they can be found at alldatadiy.com for 20 bucks. Merry Christmas!

If you would take the car to Auto Zone, ask the employee to show you where the "low pressure cut off switch" is located and ask him to supply you with a small jumper wire, it is possible the a/c charge is not enough if the low press. switch didnt come on to turn the compressor on so you need to jump it across the two wire terminals with a wire and the car running on high fan/a/c full cold, then install another can of freon and feel the cold, the system should typically hold approx. 2 2/4 cans of 134a freon to be full if it was empty.

If you have no Refrigerant in the system,you don't put any in. It will just leak out and pollute the atmosphere.
Go to a repair shop that does A/C work and follows correct EPA standards for working on air conditioning.
You can't do that job at home without proper training and equipment.
