does the compressor clutch energize? this can be determined by listening in the engine compartment for the clutch to engage. there will be a clicking sound along with the engine adjusting rpm's for the added load of the compressor. check fuses and relays. if it is not engaging. the low pressure switch also may be faulty. it tells the compressor to turn on when pressure drops. which is normal. you can test it by using a paper clip to jumper the two terminals in the connector. it is located on the same a/c line as the low pressure fill port, between the evaporator, which is in the passenger compartment, and the compressor. if the fuses and relays are good, and the compressor doesn't cycle when the switch is jumped, change the low pressure switch. fuses and relays can be found in the owners manual. if you haven't got one, download one at dodge.com.
