I have an eg with a b20 swap. The aircon will be blowing cold air in
the morning but when it hits afternoon the air doesnt seem to be so cold.
When night time comes itll start blowing cold air again. Is this cooling issues
or is there anything wrong with my aircon system. Help would be greatly
appreciated. Thanks in advance.

 

Most likely a low A/C refrigerant charge.

Does the condensor fan turn on when you turn on the A/C? 94

 

most likely its low on refrig, I have this problem with my car, I have proper refrig, and blows cold when its not hot outside, once its hot it takes forever to cool unless i get on the freeway. my problem is I need to replace the dryer and mostlikely is the condenser too
