Quoted: I added one of the small cans that you can get from Walmart. I added it slowly and towards the end of the can it started to stabilize. It would sit at 25psi for a few minutes and then go up to 40 then stabilize at 25 again. The air is cool but not cold. I'm guessing I still need a bit more. I'll buy another can and see what happens.
Any ideas on finding the leak? I've had two different mechanics put UV dye in there in the last 14 months and neither found a leak. |
Ask the technician to check the following, as both these leaks usually don't reveal any dye:
The best scenario first - your service ports where they fill the system. The schrader valves (like a tire valve) can leak, and a tech in a hurry will disconnect the hoses after a recharge and not check them with a halogen tester. It will pass the vacuum and "sniff" tests because the hoses were attached at the time of testing.
The second area, and vastly more costly to fix, is the evaporator core in the dash. It's located in the blend air / heater box next to your heater core. The best way to test this is, with a fully recharged system, place the "sniff" tester wand into the duct work on the passenger side of the car, preferably in the vents for the floor. Let the car sit turned off for a few minutes, turn the fan speed to LOW, and turn you ignition to the ON position to start the blower motor turning. If your evaporator core is leaking you'll get a detection.
