am about to replace the heater core in my '96 XJ (with AC). I have the heater core and am ready to begin, but have 3 questions before I dig in.

1) How to I safely discharge the refrigerant in my AC system? Do I just go to a local repair shop and pay what they charge are are there cheaper and ethical options (I'm in WA).

2) Are there seals in the AC system that I will need to repalce before putting it back together?

3) What else should I replace while I'm in there? Blower motor? Evaporator?

To do this legally, yes you need to have them evacuate it if it uses R12. R134A can be vented to the atmosphere. They will need to take it down to deep vacuum when you recharge regardless of which type. There is a seal you can replace on the crankshaft in the compressor if you want that is in the front. The rest are O rings and cheap that can be gotten at any decent auto parts store located at all fittings

#3 yes the evaporator core is in the same assembly as the heater core so it is a good chance to replace it. Although it isn't cheap.
