My air was not working so I pumped 2 cans of 134A in it. I had ice cold air for a day and with in 3 days Nothing. Where is the best place to start looking for a Lea

Thanks Jeff

 

Look for areas on yor a/c lines and connections for a buildup of debri ,that could be your leak. When refrigerant leaks in that volume it will usually leave an oily residue.Which will adhere dirt and dust. If you see no sign ,I suspect your evaporater core is the problem. I have seen this as a problem especially in the 3rd gen models.
