Dash probably needs to come out to get to the evaporator (if that's what you meant to say?) and I assume expansion valve too.

All the XJ's, ZG's, TJ's don't use expansion (TX) valves - they're a fixed orifice type system, so check what basic system the WH's have.
If it's a very small hole in a difficult to get at spot, then the "magic gump" leak stop IS worth trying - it worked on my evaporator (behind dash) for about 1 1/2 years. iPrior to that, in use it would slowly lose gas for about a month before needing a re-gas. But it was a very small hole in the evaporator. After drawing down to very,very low vacuum it held for one hour, similarly after pressurising with CO2 or N gas it held for more than one hour - so given that the A/C guy was satisfied it WAS a small leak and that it WAS hard to get at he used the leak sealer stuff.
In the end there were other things wrong about 1 1/2 years later and I took the opportunity to replace the evaporator and the heater core. It took most of two full days and cost about $2800 parts and labour with parts at trade prices. This was on a ZG Limited.
