Question -
I had my a/c replaced by my local mechanic.  The problem is that after recharging the system the system still wont come on and the "check engine" light still comes on.  The code is 0A21 or A021.  I replaced the part the code call for but the system still wont come on and the code keep re-occuring.  The mechanic tried to by pass something to get the compressor to kick on but that also did not work. The mechanic doesn't know what else to do.  
Can you offer any help?

Answer -
There is a:

A012
P021
R021
T021
S021
AD21
