Hello, my name is***** for the question. If I had been parked in the sun does it take a while to cool or will it not cool at all until the vehicle sits in the shade for some time?

Customer: replied 1 year ago.
it will only cool to 60 plus degrees at outlet unless it is in the shade for hours . it will cool to 40 degrees if you just run it in the shade
from the start at 70 degreees outside after about 10 minutes of running time.

Thank you. Have you monitored the pressure in the system when this is occurring?

Customer: replied 1 year ago.
no, i have not
Expert:  BOBBYSS replied 1 year ago.

That would be important to know. Most of the time when this happens it is due to a faulty low pressure switch or a failing fan clutch not pulling enough air through the condenser.
