No A/C

Hello all!
My '99 XJ has a leak somewhere in the system,after getting charged up it will blow cold air for a week before starting to subside. Cannot detect a leak anywhere even with leak detector. The only place I can't visually see is behind the dash. Do A/C lines run into the heater core. Any other options other than the complete removal of the dash.

It must be a pretty good sized leak for it to subside after a week. I'd try that stop leak stuff or of you want to fix it try the leak detector stuff

Did you add dye to the system?
