Hello, you checked the ac pressure with a set of gauges? Do you sem to have good airflow off the engine fan? If you put a rag on the front of the grill will it stay in place or fall down? Does the low side line appear very cold to the touch when the concern acts up?
What are the low and high side pressures when it gets warm
50 psi is too high on the low side unless it has factory auxillary air conditioning(rear unit)
Hello, do you need more help with this concern?
