A leak, either the pressure line or somewhere in the compressor.
all i know is that freon is put into air conditioning units in your car. it's what causes your A/C to be cold
Sound like you are low on Freon causing the compressor to cycle on and off. If you are low of Freon then you have a leak somewhere.
What causes a car to idle good and run rough when you give it gas?
You do not want it to run on low freon as it will burn itself up. There is a low pressue switch that tells it not to run if the freon pressure is below a certain point. To make it run; add freon.
Car airconditioning works similarly to the air con in your house. As freon is compressed it cools, in the lines of a air conditioner is freon. The compressor pressurises the freon in the lines and those lines run through a condensor box that has air flowing through it. Those lines cool, and as such the air blowing by them cools and comes out the car vents. This is simplistic but accurate.
where do u put freon in a smart cAR 2009
Freon is odorless; you cannot smell it.
Any AC, house or car has a pressure switch in the system so that if there is not enough freon in it, the compressor will not come on. The fan will run, but that is all. It is just circulating the air. Nothing will be damaged in the system running it without freon.
A vacuum leak is one possibility.
Freon cooler is leaking from A/C system.
Maybe you need a freon boost.
depemds on the car as how much freon it will hold. some cars have a tag saying how much freon the car is filled with. Too much freon is just as bad as not enough freon.
