Ac blows cold for five minutes then hot
Average gauge readings for R134 with air temp at 80 degrees and engine idle are 35-45 psi and 200-250 psi.

Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.
SOURCE: air conditioner blows hot cold and sometimes not at all why?
hello,seem you need to send your car to authorized dealer to scan the problem,maybe the solution is only synchronizing all the flap,ty
SOURCE: how can I fix
This is either an out of phase issue or a temperature control blend door or blend door motor actuator problem, it can also be the climate control module in the dash, 1st try disconnecting the battery for 5 min's to re-sync the climate control module, if this fails u will need to find out what blend door is the problem or if they are ok replace the automatic climate control module in the dash
SOURCE: Dodge Ram AC not blowing cold
By pass both pressure switches one at a time with small wire or a paper clip. If comperssor kicks on replace the swich that you bypassed.
if not it could be the fan clutch ot the compressor. Compressor runs about $400.00
SOURCE: 2000 dodge ram pick up - ac blows hot air and freon is good
expansion valve looks like is not openning or the capilary tube is bad
