Hi. You may have a low charge, or check the front of the condenser and look for debris like leaves in the fins or in front of the condenser. The condenser is in front of the radiator. Also if the condenser is really damaged from stones and the fins are not in good shape that can cause insufficient cooling if the refrigerant.

 

Thanks, Eric

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.
