My '93 Dakota still has its original R12 system. The compressor kicks on when A/C or defrost is selected, but, its not cold. What's the average cost to convert over to 134? (assuming there is no major parts replacement). What all is involved? I checked around when I first got the truck and prices were all over the place. At the time I decided to wait until I knew the truck didn't have any (major) mechanical issues. The heat isn't as brutal as it was in my wagon, so, I've been living with it. Now that I know I want to keep the truck, I want to get the A/C working. Aside from pricing, any other sage words of advice? Thanks.

i have a 92 dakota with the v6 magnum,when i changed mine over i just added the correct oil and fitting adapters,i also replaced the filter drier and the expansion valve and one bad return hose,drew a vacuum and charged it with 134a,no leaks and it blows cold,most people think you have to replace all the o rings,etc,i just put fresh o rings/seals where i had it apart,i DID NOT drain out the old oil from the compressor
my ladder of success is missing some rungs

What's the average cost to convert over to 134? Why not just top off the R-12? Every system leaks down with time and the R-134 will leak faster.

I am with kenworth. I used to buy into the hype about you can't mix or swap them but I saw soooo many people doing it with no ill effect I say just go for it.
I am not causing global warming, I am just trying to hold off a impending Ice Age!

Go to the local auto parts store and buy a low side 134a fitting, screw it on and buy one can of 134 with a charge hose, turn the a/c on and charge it. Groan.
