If you have screw on fittings on your A/C line it's R12, if they're quick connect lines it is R134a. At Autozone you can purchase a retrofit kit to make your's quick connect also, but you'll have to flush the system before adding any R134a as the two are not compatible and will most likely ruin your compressor. This is definitely your cheapest/most environmentally sound/easiest way to go. Good Luck!

Never flushed one myself, and to be honest don't know the whole procedure. R134a costs $5.99/12 oz. can at my local AutoZone, like Dave said you're probably looking at 3lbs. 4 oz. aka just a little more than 4 cans + cost of retrofit kit(not sure exactly). A guy came to the Zone once and said he just disconnected his A/C lines and blew them out with an air compressor. I personally wouldn't do this, but he said he hasn't had any problems.

I have been able to find small shops that will do that for around 100.00, and as far as the compressor being ruined I converted 2 years ago the enviormentally unfriendly way and have still got a good cold system and no replacement as of yet on the thing. One thing I did do however is use onlt the 134/oil combo that Wally world sells, I have to fill it with about 2 cans in the summer for a wopping total of 25 bucks but that has more to do with the fact that I am to cheap to have the thing sealed up.
Good Luck!

AMAZING what you can see when you actually open the hood. It turns out that the clutch on the AC compressor is cycling (sp) off and on every 1.5 seconds. anyone know what i should look for next?

I am not an expert so hopefully some one will chime in with more knowledge than myself on this but most compressors(if not all?) have a low presure switch that shuts the compessor of if there is not eenough pressure (i e R12) sothe comp. won't burn up.

Don't take her to the dealer, on that year truck it isn't necessary by any means. Find a small ma and pa shop, for this task it should be a safe bet and save yourself a few George Washington's....

I changed mine over to 134a. Pull the compressor, turn it over and dump the old oil out, put in the same amount (hopefully around 3 oz) of Ester 100 oil. Put it back on, pick up the conversion fittings (Napa will try and sell you a retrofit kit, but they have them separately) and screw them on. Then vacuum it down for a half hour and charge it up with 3 lbs for a 3 lb 4oz system (it doesn't need quite as much as R-12). It's also a good idea to change the dryer, but I skipped it and it works good. If you don't have a vacuum pump to pull it down, maybe you could rig up something to the one on the engine (just a thought).

My problem is time. my wife and i have a foster home and we currently have 7 children in the home. when i get home from work, (or on the weekends) my truck is always on the bottom of any to-do list. i'm gonna have to bite the bullet and find a ma and pa shop to look at my AC and change all my belts. 
someday i'll be able to wrench on my own stuff.someday
