It's not this. When I turn it to hot, it's hot. When turned to cold it's cool. So what's the ac amplifier for? Maybe it's that?When you rotate the temperature control between hot and cold, it moves a door within the ductwork behind the dash to shift the direction of the air it brings into the car. In the full hot position, it brings it over the heater core; in the full cold position, over the AC evaporator. In the middle, I think it closes both off, and either brings in fresh air from outside or recirculated air, depending on where you have that slider positioned.
Checking it requires some dash disassembly. The FSM calls it the "air mix damper control."
Can I go ahead and buy the amplifier and pressure switch from you? Really appreciate it.Remove and Replace. I can send you the extra AC Amplifier I ended up with for $30 shipped. I tested it in my own xB, so I know it's good.
I assume the AC Tech you had check Freon also checked the Drive Belt tension as Steve indicated on his list. If he/she didn't, check that first since that is a not cost check.

If after checking/doing all the low cost or no cost items on Steve's list and still not getting cold, all that is left is a high cost AC Compressor rebuild in your future.

I also have an extra pressure switch left over from my Diagnostic process I can put in the same box if you want to also swap that out.
