Check to ensure you have proper refrigerant charge in system. If properly charged check the following:

Fuses:
F2.19 (25A) – CJB
F1.7 (30A) – BJB
F1.25 (10A) – BJB

Relays:
PCM Power Relay – BLB
A/C Clutch Relay – BJB

Switches:
A/C compressor cycling switch – Low pressure line P/S by receiver dryer
High pressure switch – 3.0L High pressure line D/S near battery, 4.0L High pressure line D/S behind compressor

best way to see if the electrical part of the a/c is fine is to jump the wires together at the cycling switch, if all is ok, the a/c compessor will turn on.
