A/C Leak - Drain water has dye in it

My a/c system is leaking freon - about a pound every 10 to 14 days. I put the UV dye in a few days ago and went hunting with the blacklight tonight - I didn't find any direct evidence of the leak, but the water coming out the a/c drain pipe had a significant amount of dye in it.

I thus deduce the leak to be in the evaporator. Am I correct? Could it be some other component in the dash? Is there any easy way to check without spending the 4-5 hours necessary to take the dash completely apart?

The car is a W124 (93 300E 2.8)

Thanks

Sounds like it is time for the dash to come apart to me.

The expansion valve is easily accessible in the engine compartment. The lines that come in and out from the evaporator are as close as one gets without taking itv apart.

Not exactly the news I wanted to hear. I guess I'll probably try that cryo seal product.... either that or just refil it every time it gets low. I can't afford the $2700 it takes to replace it, and I don't think I'm capable of doing it myself.
