The Good News: My wife decided we need to keep our 89RR when our Jeep GC goes back to the lease company. 
The not so good news: so now I have to work out the two main bugs; getting the AC recharged and high temps up hill.
#1 It's my understanding that the whole AC compressor or coolant needs to be upgraded to a new government standard. Is this the case with a 89 and what exactly do I need to get?
#2 When going up mountain passes and even on small hills on hot days, the needle goes up to the red and the only thing to stop it is to turn on the heat, roll down the windows and ease back the speed to near crawling (which sucks when you have friends following you). I'm assuming I just need to give the radiator a good flush, check for clogs and all the hoses. Is there anything else that would cause this repeatable jump in temp that I should look at?
thanks

1. Garbage. I still have the original A/C and when charged up it works fine.
2. At it's age, just replace the radiator and be done with it.

If your coolant level is not low(leaking out), then you may as well plan on replacing your radiator. Some time can be bought by removing the thermostat, which will restore some of the diminished flow thru the corroded radiator.

Peter,
If you're repairing your A/C for any reason.I'd recommend convert it to R134a refrigerant.It'll cost you less in the long run.R134a is $5/lb or your old R12 $40/lb.Also,R134a is ozone friendly.(for now anyway)

thanks for the info.
Ah yes, it was the conversion to R134 that I was thinking of. That's the conversion cost I needed to look into.

Peter,
Just had the A/C on my '93 re-charged with the old R12 and it blows real cold. The old stuff actually works better.
Agree with P, best bet is just replace the radiator and associated hoses. Had mine done and even in Tulsa triple digits never gets hot.

Do NOT convert to crappy R134A - it's just not that good, especially in a system designed for R12. You will also lose it quicker in an older system due to old hoses, seals, etc. R134 is comprised of much smaller molecules than R12.
You have two options IMO - pay the $40/pound for the R12 recharge - have the system leak tested first so you don't lose any of that precious stuff! Also - if the system has gone dry or been exposed to air - replace the dryer - it only costs a few bucks and is worth the effort.
Second option is to put in the new FR-12 - it is harder to find, but not as expensive as R12 is now. It can also be mixed with any R12 left in your system if there is any. It is compatible with the R12 designed system and will cool better than R134.

Hmmm.....after giving it more thought and looking around, I've decided to stick with the R-12 because hay, I live in Seattle and we just don't use it that much. Even at $40/lb it will last a good long time before I need more. I'd say I use AC maybe 1.5 months a year.
thanks again for all your input.
Now to find a good AC shop in the North Seattle area...
