How do you fix p1464 code in a 2001 ford f250?

Answer 1

You need to determine why the code was triggered first. One of the most common reasons is that during the self test, either the a/c or the defrost was turned on. If you get the code cleared and it doesn't return, it could be as simple as that. Since you have the code, I'm guessing you are already working with someone, but if not, places like Carx and Pep boys, typically will pull the code and clear it at no charge. If the code is triggered again after it is cleared, and the a/c and defrost were not turned on, it could be one of the following:

- A/CCS circuit shorted

- A/C Demand Switch failed

- WAC relay has failed.
