Whenever I turn on the A/C of my pick-up, I just noticed that the coldness varies on the time of the day specially now that it is summer. on medium A/C from 10am - 4pm, it is not that cold. but from 5pm onwards, it becomes cold. I actually turn the A/C to low because of the coldness.
my question is, are there any problems with the A/C system of my car? is flushing the answer to the problem? or adding freon?
When was the last time you had your air conditioner cleaned? It may be the culprit why your ride's aircon is not an optimum efficiency. While you are having your aircon serviced, you may check your expansion valve and drier, they may need replacing for a better cooling effect. Good luck.
