Just had my clutch replaced by my trusty mechanic a few days ago.
Today, it was finally warm enough to use the AC so I hit the button but nothing happens. The blue light inside the AC button turns on, but I don't hear/feel the AC compressor crank, and obviously no cold air blows out.

I know the AC was working before the clutch change, because I run the AC twice a month during winter for a few minutes each time just to keep the hoses/pipes lubricated.

It's just too much of a coincidence that it stopped working after a major job, which required taking apart a good portion of the front end.

Could it be something simple like a wire that's not plugged into the harness?

why not take it right back to that trusty mechanic and have him figure it out....since it's essentially his responsibility if it worked before he touched the car.

1. It's Sunday
2. He's 50 miles away (I only go his direction a couple times a month)

SO you are saying that it IS blowing air, but not cold? Also you cannot hear the compressor clutch engage?
I would check the connections to the compressor. Also the fuse or fuses. Thats easy enough for you do do.
Another thing is that you might be low on refrigerant, causing a low psi in the system not allowing the clutch to engage.
If you cannot find the problem, you are going to have to take it back to your mechanic.

Exactly.
Freon was added last summer so I doubt that's an issue. No leak was found when freon was added.
Will check fuses and connetions.

thats probably your problem... don't use freon, use r-134a. using freon in an r-134a system will ruin all the seals in your a/c system and the refigerant oils aren't the same.

Doubtful.
The compressor does not crank at all.

could have siezed up because you didn't use oil for r-12.
