My AC blows slightly cool air, Hafta check the pressure... I also hear a slight 'clunk" from behind my head every few seconds (sounds like something's opening and closing?)
("short cycling"?)

The clunk you hear is the system cycling. You're probably low on refrigerant, and if the stuff on Ebay is real R12, and you can get it at a decent price, you might as well go for it.
My neighbor was telling me there is a substitute for r12 now that is just as good and will work in an unmodified r12 system. Anyone else heard of this?

FieroMonkey, isn't there another thread going about "freeze 12" right now? That's probably what you're thinking of. Maybe its in GFC...
--------- I'll also say, if you plan on keeping R12 in your system, mark it as such. You don't want to be the guy responsible for damaging a shop's equipment because they didn't know you haven't changed over to the enviro-hippie approved stuff.

Lots of eBay sellers will sell it to you 'for resale' or whatever. I got EPA Section 609 certification so I could legally purchase it without worrying about the feds knocking on the door.

No other refrigerant is just as good as R12 that will work in an unmodified system. There are many that are "good enough" depending on the integrity of your system. But there are some that are downright dangerous, (I'm thinking highly flammable concoctions) and many are illegal.
The best substitute today in my opinion is good ole R134a. If you go with one of the more exotic mixtures you render your system untouchable by any reputable a/c shop.

I've been using a mixture of propane and isobutane in my vehicles for 8 years. Very cold, easy on the system.
Aside from the fact that they are illegal you guys have way more guts than I do. Everything burns if you get it hot enough, but as leaky as my systems are there is no way I would be running a mixture like that in my cars.

The combination of propane or butane and refrigerent oil when ignited has the potential to cause a lethal fire explosion. Since the A/C lines come into the cab, you could be "roasted turkey" in seconds. Also be advised if you get a fire due to the use of an illegal refrigerent, you have NO insurance. Your policy is only valid when you comply with the law ,same as if you are driving around with an expired inspection sticker. If you get into an accident that is your fault, and even if no fire results, if an investigation reveals that butane or propane is in your A/C system, you have NO insurance coverage. They will come after all of your assets and get them. Is it really worth the risk when R-134A is available and works very well? Propane, Butane, Enviro-Safe are fire bombs waiting to happen. They were meant to power gas grills and stoves, not an A/.C system.

You ever see a Propane truck on fire? I have it just burns. doesn't explode. Not saying it's the safest thing but the fuel tank with the Electric Brushed motor in it is far more dangerous.
