First the low side port should be identified, connecting w/ a set of guages- apply at least 28" of vacuum for ten minutes. If the reading on your guages (vacuum) moves (loses) vacuum in 15 minutes don't charge the system- you have a leak. If the vacuum guage doesn't move (leak) then charge with the proper amount of refrigerant gas.

Check charge. (R12)
Should be 2 ports on your ac lines somewhere. they work like tire valves. You just plug in a can of r12.
You buy r12 at auto parts store then plug the can into a valve on your ac line. instructions will be on can.
Not the high side.
Would have been built for R12, can be converted to R134a.
I believe it is around 3 1/2#.
The cost to charge an air conditioner in a Chevy Silverado 2005 truck, will depend on if it has a R-12 or a R-134a system. The truck should be taken to a mechanic who can charge the AC and who can also given an estimate of the cost.
The 1990 Ford F-350 requires 52 ounces of R12 refrigerant. This is applicable to all engine sizes of this model.
R12-if it has ac of course.
easily. Buy a converter from local parts store for r12 to r134 system should cost 6-10 dollars. Screw converter onto AC fittings and charge as a normal system Freon is about the same cost.
"Which fuse controls the fan for the ac on a 2006 Chevy silverado?"
R12 unless it has been converted. I would convert it over to R134 due to the price of R12.
You have to have a permit to buy R12 and it is very expensive. Any system that uses R12 can use 134 the replacement for R12. You will need adapters that screw onto the old fittings that accept the hose that hooks to the 134 can. You add freon to the low side of the system. The adapter are different sizes so you cannot put it in the high pressure side. Yes, if you have any mechanical knowledge at all, you should be able to charge the system without much trouble. OR you can buy all the R12 you like for cheap from Mexican sources and keep the longevity of your original equipment and lower operating pressures of R12. They way your system was designed. R12 comes in everyday by the truckload thanks to our new open border laws.
1993-94,depending on the automaker.
R12 is original equipment
R12 I owned a 91 Volvo 240 with inop AC for 6 years. I refused to get the R12 system fixed because of the damage that R12 does to the ozone (it is also expensive and restricted in distribution). I just sold that car last week and got a car with an R134a AC system..........I feel better. == == == ==
I would suggest you take the car to a professional for the conversion. It is illegal to release R12 into the atmosphere. R12 is very expensive and it can be recovered with the proper equipment. You also need to have the oil changed in the compressor. You would not be considering this unless you had a leak. That leak must be repaired before charging the system. You may be able to work a deal with the shop, where the recovered R12 may pay for the conversion. Any R12 left in the system is valuable, so remember that when talking to a professional.
r12 is the original refrigerant on a 1993 model year Prizm r12 is the original refrigerant on a 1993 model year Prizm
YOU WILL NEED TO FLUSH THE SYSTEM TO REMOVE THE OLD OIL. ALSO INSTALL A HIGH PRESSURE SWITCH AS REQUIRED BY THE EPA. THEN INSTALL CORRECT AMOUNT OF OIL COMPATIBLE WITH R134A. CHARGE TO ABOUT 80% OF R12 BY WEIGHT.
You charge your vehicle ac system through the low side port on your ac system.If you need more information about adding refrigerant to your vehicle, or retrofitting a car from R12 TO R134A you can go to www.idqusa.com.
I would be surprised if it was anything but R12
Should be R134
