I have a 90 Teg and the A/C is blowing warm air - is this only a matter of adding "Freon" (sp?) - any shops licenced to do this?

Freon isn't "used" by the a/c system. It is like coolant to the engine.
If freon is missing from the a/c system, there is a leak. Have it diagnosed. Is the compressor working? Or is there a leak?
Find out the reason behind the warm air, THEN fix the problem.

Adding freon, or the equivilent refrigerant, won't help if you don't know the problem.

you could probably do it yourself.. they have kits for it

I checked the compression last night and its at 0 psi - looks like its more than just a leak

Add dye to the system (around $30 and glows under black light), run it for a little while, then check for leaks.
Is the compressor running when you turn it on?
