Doubt it is easy to medium.
It has been suggested here that it is only a maybe.
The expectation is that the complete evaporator/heat-exchanger box
behind dash would have to be swapped out.
Then all the electrical for the newer model. Having a donor car handy would be a plus.

The $550 to $750 replacement system was on my list as a choice. It seemed, in the long run, to be the best no hassle sure to work a long time solution.
I plan on driving my car another 10 years.
But... I was able to get my hands on an aluminum bodied servo valve and amplifier for maybe $300 (the aluminum valve is currently $600). It worked and now I am pleased. Part of the installation included repair of broken vaccum line going to the old valve.

When my valve originally broke I went several years with just a bypass hose for winter driving so I could get heat.
My AC worked even with a busted valve.

So, if money is tight, bypass for less than $20 to get heat.
If you can acquire a replacement servo (and possibly the amp), it is a no hassle drop in repair.
If the price for those parts starts getting up around $500, get the kit and never worry about it again.
