How do I recharge the Air Conditioning on a 1995 Lincoln Continental?

Question

Someone said if the refrigerant gets too low, the AC compressor will stop turning itself on, so recharging is futile because the compressor won't run. They said that I would have to short something in order to get the compressor running again to circulate the new refrigerant. Do you guys know anything about this? If you do, how do you go about shorting the compressor? Thanks for any help!

Answer 1

you,d be better off letting someone do this that has a set of pressure gages,and this way they can check the amount of pressure on it as they charge it,too much pressure and it will damage the compressor on it,and not enough and it wont put out enough cold to keep it cool inside,good luck with it.

Answer 2

did this system recently work? if so goto the autoparts store and buy a can of 134A refrigerant with the hose attached open the hood the hose will only fit on the propper fitting on the A/C system (the low pressure side) this should be located some where between the reciever dryer and the compressor. Start the car with a/c on open the valve allowing
refrigerant into the system. If it was not recently working the system will have to be vacuumed down and leak tested by a qualified professional A/C shop. Be prepared to spend some money though depending on that the diagnosis is.

134A is still legal for purchase in Florida...

Answer 3

Since it seems you don't know much about mechanics, better get a pro. For your information: It is true that if the refrigerant level gets low the compressor stops, but all it takes is to get the pressure up again and it will run. If the refrigerant is low, there is probably a leak, so there is no point in recharging it. However, in Wallmart and many other places they sell kits to recharge the system. If there is still some pressure, however low, it can be recharged. If there is no pressure, then it has to be "vacuumed" with a suction pump. If you don't know what I am talking about, don't mess with it.

Answer 4

Under the current refrigerant-sale regulations you can not even get a can or refill refrigerant unless you are a licensed technician. Then you need an appropriate machine to pump out all of the existing refrigerant, check automatically for leaks, and then add the old plus some new. So don't worry about what to do after adding the refrigerant because you will never get that far unless you are a licensed pro.

Answer 5

AC systems are under high pressure. If you aren't sure of what to do, I recommend taking it to a reputable shop equipped for AC work. Better to pay someone you trust than to be hit with high medical bills for injury for doing it wrong.

Answer 6

First the old crap needs to be recovered - (vacuumed out)

Then check for leaks - (dye test) with ultra violet light)

Then once the system is sealed and cleared then it can be re-charged with the new:
R-134A

Answer 7

there is a switch on the receiver/dryer you can unplug and jump.people say you can't do it yourself without a license,but if thats true,why do they sell it at walmat?and you don't need to pull a vacum to top off a system.
