Thanks a million for all your help!
My 300 TE was charged with 134 refrigerant last summer. After charging the A/C, the tech checked for leaks using a handheld device. He poked the leak tester in the driver's side, center and passenger side air vents. And all three air vents sounded indicating a leak. According to the tech, my evaporator is leaking. The cold A/C air disappeared after one week. I still haven't had the leak fixed due to the high cost to fix it.
Is the leak really coming from my evaporator or could the leak come from other parts?
