01 Lincoln Ls V8 (Climate Whistling Noise)
Ls has sum type of whistling noise coming from the passenger side every time i turn on my climant on hot or cold I can hear it.I recently change out my heater core on my Ls. My refrigerant empty out when I disconnect the a/c hoses. I have since recharge my a/c i put about 12oz of coolant in it to test for leaks. I did notice that the gauge read that the car had sum refrigerant in it before I recharge it. The whistling noise started after I did the heater core change out.
