Re: R12 to R134
You have to have the R12 completely evacuated. This is done at a repair facility that works on A/C. The only thing after that is screwing on 2 fittings to your existing lines and charge your system. Companies make retro-fit kits so the owner can do it themselves. These kits are available at most part stores.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Mechanic (only for users in the US for now) and get all the help you need. Goodluck!

This car originally contained R12, if you can find it you can use it. The other option if this has not already happened is you can convert the system from R12 to R134a, which is readily available, all auto part stores carry these kits. R12 AC fitting are threaded and R134a systems have slip on quick connect fittings.
Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle.
Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power.
Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High
Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can.
Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood.
Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
in 1986 it is r12 but you can convert to r134 which is a ton cheaper than paying for r12 you need a license to buy r12 r134 is right on the shelf at auto zone they also sell retro fit kits with everything you need to convert your system and they work very well
Must be Air-Condition System Lines/ Hoses leaking R12 Freon (gas). MAYBE THE PULLY HUB BEARINGS FAILED OR DUE TO VERY LOW R12 FREON (GAS ) will not work. Because there is a switch in the receiver/dryer prevent AC from working when low R12 Freon present, to protect the system & compressor damages. You must fix the leaks, before recharging it. They must **** the old (residue) gases from the system & lines / hoses...... & stay in the vacuum pump 30 minutes to proof no more leaks. Recharge some oil for the old type R12 Freon gas. Before recharge it to 62-67 psi R12 Freon See the web site like www.youtube.com/video site to see How they service & repair air-condition system? Put the question to their search window. This is the question u should. How they service & repair air-condition system? Regards; MAR
Depends on if it takes R134 A or R12 refridgent. R134A most likley looking around $150 depending on amount of freon the system holds. if its R12 open your piggy bank cause its going to cost you some coin as R12 is no longer in production you have to convert your system to R134A or find a gararge that still has some R12
Sounds like the A/C system just needs to be recharged. When was the last time you had this done? Just take it in to your mechanic and he can do it for you and if that's not it for some reason, then he will be able to find the problem but most likely you need more freon added.
