I am replacing the AC Compressor on my 1999 Chevy Lumina 3.1 with a rebult. Will I need to recharge the AC system and if so, what is the cost associated with that?


Once the repairs are completed the system should be evacuated and held under vacuum for at least 45 minutes to an hour to boil off any moisture that has accumulated. It can then be charges with the appropriate amount of refrigerant. Moisture in the system can cause it not to function correctly.

If the system has not been operational or the compressor failed internally the receiver dryer/accumulator should also be replaced. Most compressors are not warrantied if the receiver drier is not replaced.

Condensate leaking on passenger side from ac


The drain tube from the evaporator housing is most likely plugged up. With the vehicle in the air locate the drain tube on the passenger side of the firewall and using coat hanging or something similar carefully snake it through it Be careful as a lot of water may pour out and don't go crazy poking with the coat hanging as the evaporator core is at the other end of the tube.

I have a 1999 chevy lumina and it overheats when i am just idling and the ac is on.


This problem can be caused by a faulty cooling fan, lack of coolant circulation thru the radiator ( bad water pump, partially closed thermostat) or a partially clogged radiator. Make sure the radiator and condenser in front of the radiator are not full of dirt and clogging the air flow also.
