Replaced A/C compressor and 2 days after A/C been intermittently blowing cold then warm. No certain pattern, just does it throughout the day. Sometimes I'll turn off A/C and turn it back on and A/C will blow cold, but after a while will blow be warm again and comes back cold.

Good morning,

Did you change the dryer and evaluate the system for about 45 minutes? It sounds like you may have moisture in the system.

Can you tell me the high and low side pressures while the engine is running? You can rent a set of gauges at a parts store if you do not have a set.
