Hey guys, looks like I need a compressor for the Century. Anyone have a good one? I think it's "H6" style.

HR6 or DA6 style is the designation.

I would recommend on this car that you buy a reman compressor from a reputable source. These are finnicky and the chances are a used one (unless pulled from a charged system) will have dry seals and internal corrosion.

What is it doing wrong?

I had it checked out because it wasn't kicking on, and I'm told it has a blown seal. The shop wanted to completely rebuild the entire system and convert it to 134, to the tune of $1000. http://i42.photobucket.com/albums/e302/leftventricle/emotes/emot-gonk.gif Not a terrible price, honestly, but I sure as hell don't have that much money sitting around anymore.

My advice?

Change the drier. Put 6 ounces of PAG150 oil in the new dryer.
Evacuuate for 2 hours minimum. (extra time since you are changing refrigerant type)
Install one can of R134A with leak-sealer, and 2 cans of regular R134A.

It will cool fine; and either it leaks down or it does not. Try this before spending all that money.

Yea why would the compressor be bad. It doesnt kick on because the low pressure switch is seeing low charge and now allowing it on. Look for a oily connection or fitting, or for a badly damaged condensor ("radiator" for the a/c) They take some hits from rocks and collisions and even high curbs. id locate, and quick fix the leak, and recharge it. I have to admit i have never vacuumed down a system and have done like 7 "ghetto retrofits" is what i call them. New acumulator, orifice tube, find the leak, fix it, fill with retrofit oil, R134a, and a shot of UV dye. They blow pretty cold for retrofits.
