You have an '88, has it ever been converted from R-12? Because if not I can be almost positive that you have the wrong Freon Charge. R-134 and R-12 do not mix well, if at all.

Check the vacuum lines and make sure the blend door is not screwed up. Are there bubbles or noticeable flow going through the sight glass near the receiver drier?

On an 88 the blend door should be cable operated, just look under the dash at the lever and see if the cable is still on it

sorry i wish i knew the answers to at least one of those questions
I don't know where the blend door is at
and i dont know if its ever been converted from a R-12

Then you should take it to a reputable AC shop.

Unless you're certain (sounds like you're not) that it's been converted to R-134a, you should *NOT* mess with it. Look for a sticker on the compressor that says R-134a. Also search for R-134a adapters and see if you have anything that looks like them on your compressor.

Any refrigerant you've bought will be R-134a as R-12 is not legal for sale in the US unless you have an EPA certificate. Most likely the hose end on the cans you have will not fit on fittings on the compressor.
