RTH - Head Gasket complete - AC compressor won't work (2 Viewers)

[nicksr]

So, my mechanic finished my head gasket and timing chain slipper and called me to pick up my truck.

When I got there, he says "I assume the AC wasn't working when you brought it in". Uh, no it was working just fine, thank you.

So, now I am running short of time and trying to help him out.

What are the most likely reasons the compressor wouldn't work at all after doing the HG?

He didn't plug in the pressure switch would be my first guess and easiest to check.

I just was wondering if what the solution was here? Just got truck back from shop and new head gasket but no ac. Relays in glove box seem to function, freon is full, compressor runs when 'jumped'and blows cold. Plugs on compressor and pressure switch (by usds battery) reset.
Any possible thoughts? I can't complain as much as some, it was only 102* here today.....
