If you paid a shop to replace the stack of parts mentioned in your opening post and you have no cold air after all that work and your $$$$, I would take it back and DEMAND that they resolve it.

That aside, there have been many posts here about 126 owners converting from the original R-12 to the newer R-134A. Not many have been pleased with the outcome.

I do not believe the refrigerant issue in itself is your problem because you say no cold air. However, if the shop you used improves upon you current situation, do not be surprised if you never feel like the system is really getting it done.

As far as I'm concerned, R-12 is the only refrigerant to use in a 126 car.

Just my 2 cents.
