Hello! I have two problems... some background:
2001 Explorer Sport, just had the evaporator replaced and the system recharged.
Problem 1: Noticed a few days ago that when in Max AC and the engine under load, the air flow shifts from the vents to the defrost vents only. I suspect a vacuum leak, but anyone have a idea as to where I should start? Also, this only happens in Max AC... in normal mode it seems to work fine.
Problem 2: Since the replacement, I hear a high pitch noise coming from the evaporator area when the AC compressor is running. It almost sounds like a fan motor whine, but since this only happens when refrigerant is running through the system, I have ruled out the fan motor. It continues and gradually fades when the compressor is turned off.
Thank you for any help or ideas you can offer!
