AC Repair - can we say blow cold!

Had to replace the dyer, filter, and bearings ... I can now say it blows cold. As a matter of fact - all the way set to cold is actually to cold for the cab. Who knew the factory GM AC unit could blow this cold. Also they used R12. :metal:

Yep...I use nothing but r-12 in a factory AC system, as it was designed for. Ice cold air no matter how hot it is outside :metal:

I still think R-134 with a parallel-flow condenser (which isn't stock, of course) is even colder...

But what about R-12 with a parallel flow? That'd be cold. I've just never seen it done!

Possibly but ... I wanted to keep my AC as close to stock as I could.
