first check and make sure you are getting a signal thru your low pressure switch on passenger side ac line. if your not then you are either low on 134a or you have a bad sensor

yep, without that your ac will not work. It will set a code in the computer but not kick on the light so with a decent scan tool you can find out easily if thats your issue.
