Message:
I had my a/c filled w/ R134a & yellow dye a week ago. Worked fine for a few days - now the a/c is short cycling and not cooling. I'm assuming there's a leak, but I can't find signs of the yellow dye anywhere. There's also a nasty mold smell coming from the vents when I first turn on the a/c. Does anyone know where to start troubleshooting to find this leak? All I notice is the normal condensation drip from underneath. Appreciate any help on this - I don't want to spend another couple hundred bucks if I can avoid it. Thanks.

maybe you need a blacklight to see that dye?

Yeah, I've tried the blacklight, but can't trace the source of the leak. Must be hidden.

Sounds like the leak is in your evaporator if you can't find it in the engine compartment. That sucks!!!!

Is the evaporator difficult to access?

Having the same trouble. Had it checked today and they told me the compressor clutch is failing. It is not staying engaged when the electrical signal is sent to it.
