Question about 1992 Chevrolet Beretta
Wanting to replace a/c in 1992 beretta that no longer works.what parts do i need?
If you replace the ac,you need to find out whats bad first.To see if it needs a charge only locate the pressure switch on the air dryer which is a silver canister with a plug on the side of it with 2 wires,when you unplug it and look at the plug you will see the connectors,use a small piece of wire to jump them together,turn on the engine with the ac on and if the compressor kicks on then its out of freon,then the o-rings in the lines need replacing.Note that its probably a r-12 system which if there is freon in it,it will have to be evacuated or sucked out first,and you will have to change the air dryer,which new is about $90.00 at the autoparts store.Even if the compressor is bad and you have to replace it you will still need to replace the air dryer because you will have to charge it with 134a and it does not mix with r-12.Also there is a filter behind that switch on the air dryer called the orrifice that can be plugged and the ac wont get cold enough no matter how much freon you put in it.Its a job to fix them and it takes time,but its worth it and remember to replace all o rings when you re-charge it so you dont have a leak and waste it,which there is a dye to put in the system that comes out the leaky seal or line.
