/*1y A/C decided to stop woking a few weeks ago. Me and the girl will be taking the stang to Lake Havasu this weekend and it's gonna be pretty dang hot! No way i'm driving up there with no A/C! Any ideas why it would stop blowing cold air? All the lights turn on and the fan blows but no cold air.. Thanks

Definitely the a/c clutch isn't engaging is my bet.
Now, the reason is many:

This could be due to a bad connection to the clutch.
A bad clutch.
A bad A/C compressor.
A bad pressure switch (there's two, high and low)
A *correct* pressure switch, likely the low, and means the refrigerant is low.
A differently correct pressure switch, likely the high, which means the system is clogged, likely at the expansion orifce tube due to crud.

Which of these is the answer? Only a set of gauges will tell ya. And if you don't know how to deal with those, then it's best to take it to a decent A/C technician.

And if it's the refrigerant, then the question becomes why is that? Where is the leak?

Hopefully, it's simple, like a hose. If it's inside the dash? Ow...

/I'm sure I'm missing something... but not much, methinks.
