Hi, I recently replaced my A/C condenser and recharged my system and the A/C works good while I am cruising down the road, but I let it idle for little bit the A/C turns to heat. The engine fan appears to be working right. The engine does not overheat and the aux fan I can hear kick in from time to time. Thank you

Good morning,

Did you replace the dryer? That is required when any part is replaced.

What are the pressures of the system when it is running? I need the high and low side
pressures.
