AC doesnt work.

[amit]

My Chevy AVEO AC was not working. the mechanic checked it and did a direct connection and it started..but in normal condition it would not start.. After a lot of work around, he found the problem and told me that the control module need to be changed (this he sd after replacing the same from on of the cars). Im enclosing the pic of the module that he sd need to be changed. Can anyone pls advise..
