When the one in my 2000 was not working I bought a sniffer and charged up system and found evap core was leaking figured since I went thru all that trouble of removing the dash why not go ahead and do a complete rebuild I replaced everything except for the condenser (everything was original) I just removed flushed it out. One thing I did notice and took me a while to figure it out was if I open the valves on lines (open/closed valves on end on hoses) at schrader valves afterwards when lines remove they would always develop a small leak but if I open most of the way after removing them never leaked. Figured somehow the stem in the valves were getting damaged somehow if I open all the way till bottomed out...figured just cheap schrader valve as my gage set is not a cheap one and was new.
Rambler65 do you have a suggestion on a good value unit ? I still can't find a leak. Would not mind trying this option.
I've had my electronic detector for quite a while now, not sure about what's currently available. A quick Amazon search shows refrigerant detectors available for around $20 up to hundreds of dollars. The following unit is $50 and has mostly good reviews (if reviews can be believed). At least with Amazon returns are easy if it doesn't work:
The thing about UV dye is it only helps if the leak is in an accessible area. On the XJ if the leak is in the evaporator you won't see the dye unless you remove the dashboard to check it. If you're going to do that you may as well just replace the evaporator, and the heater core for good measure.

My dtector I have had it for a while and is the TEK-Mate brand. Its a little more money but I'm a firm believer you get what you pay. Also true on the dye.

got a link to it ? Couldn’t find it on amazon.
I’m in the middle of a rear main seal replacement and upgrading the battery cables again. Houston’s Coastal weather creates a bunch of rust issues.
