A/C Questions

Hello Guys, I have a few A/C related questions and maybe one of you can help me out. The truck is a 2003 6.0 Diesel. ( I know a 6.0 )

The A/C works fine and it has cold air while you are moving, when you are stop or at idle the air coming out is not cold, today, I took the truck to the local A/C mechanic and he claims that the A/C Fan may not be operating correctly, according to him when the truck is stop or at Idle there's not enough airflow been drawn therefore the air coming is not going to be cold, he also mentioned that due to that, the pressure was too high.

According to the tech, the A/C fan operates electronically as needed and that I need to hook a computer to the truck to see if the signal and commands are working correctly.

Does this sounds right? Is the Ford dealer the only one with a scanner for this particular troubleshooting? Any comments

i dont think having a 6.uh-oh makes a difference. but having a secondary electric fan on the condenser will make a difference. i swapped from a clutch fan to corvette electric fans on my silverado and my ac works much better.

you can also check to make sure there is not a buildup of dust/debris on the condenser.
