After 3 days in the shop I got my car back late friday afternoon.  The air coming out of the vents was icy cool and I was overjoyed.
Today (Monday) it's crapped out completely again.  
I am NOT in a very good mood considering I've now given this shop over $1000 over the course of several months and gotten NO results.  Anyone have any other ideas?  Anyone think I have any chance of getting some of the money back?  Perhaps I'll just take it to a dealer and see what they say...
Edit:  I found 
this online, perhaps I should print it out and bring it to them.
