Well, it is not too easy to shut up :))

ZT "as long as fan workes, or the car is moving, condenser will work no matter how high the temp in radiator is."

Are you sure? Do you never see that an AC condenser has been totally blocked by dust or objects?

ZT "it could be anything, no one can tell until u got high pressure and low pressure reading."

If you have some knowledge and experience, without gauges, you still can tell what is happened.

 

Have a nice day. :))
