Whenever you add Freon,you are suppose to leak test first.Your compressor is good,you have a leak somewhere.A good place to take it to is Midas,they changed my freon over from the old stuff to the new R-134a,they leak test it first,that is rule 1 when adding freon.

i cant give a direct answer i can only ask questions has anyone been under the dash put radio in heater core anything and knocked the vents loose do you hear air hissing or vacumm leak check fuse box for heater vents a/c vents blown fuse look under hood if you hear air look for loose hose going to firewall

Depends on what is clicking. The engine vac opens blend doors under the dash. It could be one of the vac pots or a blend door is sticking. Normally the hissing noise means you have a leak, but a leak usually does not fix itself.

you obviously have a air leak, check for cracked pipes on the driver side but mostly it will be a connector that is leaking

Take it to a shop and ask them to check your brake vacuum booster.

Sounds like you have something rubbing, since you are not loosing air and there is nothing else to hiss,, an exhaust leak would have a different sound. I have seen debris get wedged in the brakes and make a noise when you are underway. The sound would vary, depending on what sort of debris it is. I would remove the wheel and look for the culprit. Your brakes may need to be religned as well. Sometimes the audible brake wear sensor will make a noise like that. Good Luck! I hope this is very helpful!

Sound like a leaking hose to me or a leaking water pump, for me to help I need to know exactly what's leaking. Check it out and let me know. Good luck nd thanks for using FIX YA

You need to clear the condenstate drain for the AC evaporator core, it is under the car, as far as the hissing, sounds like a vacuum leak, look for a disconnected small hose around the area of the noise.

yes that is the expansion valve! there is a hissing sound from the restriction in it for a pressure drop thats what makes the a/c cold the hissing is normal
