Whistling AC


I hacve a 2007 Chrysler PT Cruiser Touring Edition, 63000 miles

The radiator fan assembly was just replaced to fix a problem with the ac not cooling and the fan not spinniung at all speeds. MProblem fixed but now there is a whistling noise coming out of the passenger side vent when the ac is on the car is in motion. This noise does not happen when the car is stopped or the ac is off.
so far I have been told it needs a cabin air filter, the high pressure relief valve needs to be checked or the HVAC has a leak or bad hose.
CAn someone please telll me how to check these problems or if these are problems associated with the noise

Do you
have the same problem?
