The car does use R-134a, i would have a AC shop check it out. NEVER use those R-134a DIY refills at the auto parts store - they do more harm than good.

Why do you say that? the guys at the shop use the same exact bottles.

Same problem on a ES300, cool but not cool enough on a really hot day.
Turns out a check valve was working off and on. It took the shop the good part of a day checking it over and over until it malfunctioned for them. A $39.00 part..$240 labor, Working good now.

When you say Check Valve do you mean expansion Valve if so does anybody know where it is on a 1995 Sc 400

Not sure of the slang used to describe the part. The part number was SCS208293 Labeled on the invoice as.."Txv 2000-93 Toyota Blk". Not sure if it was a OEM toyota part or aftermarket. It was an independent A/C shop that did the work.

not virgin refrigerant, R-134a is the SAME no matter what label, as DuPont and Ineos make R134a in the US. I'm talking about the all in one cans you charge in yourself with oil, system sealer, O-ring additive and cleaner. Those will ruin recovery machines and might ruin your system.
