The AC compressor uses a chemical refrigerant known as freon to cool air as it comes into the cabin of your car. This chemical can leak out over time and as it leaks, it turns to gas, so you can't see it leaking out. If you turn on the ac and just ambient air comes in, you can your Air conditioning recharged, and see if anything improves.
Your A/C compressor is shot. It's internal computer (or that of your car) is malfunctioning. The "jerk" is when your "A/C" kicks in...an A/C compressor takes much of your cars usable power. As it turns on and off you will get the hiss and jerk. (the hiss comes from the overworked compressor lines cooling)
There are a few possible reasonsÊthat an air would only blow cold when accelerating. The top two reasons are that the compressor fan might be malfunctioning or that the compression clutch isn't engaging.
try a new thermostathard to believe but all a/c have one
ONE OF THE HOSE WAS BROKEN AND NO ANTI-FREZEE
No, without a turbo, there is no blow off valve. However, if you really wanted to, they have fake blow off valves for sale. These mimic the sound of a blow off valve. It would be an absolute waste of money, but hey, it's your money.
it either needs new rings on pistios or one piston is cracked causing blow by or ... blow by is when compression escapes your piston..
It might blow up. If not, then a part of it may blow up or the compressor piston may blow the seals. Either way, it can cost you money.
Use a air compressor and blow the lines out. This almost always works.
Stop being a ricer and give your grandma her car back. If you want a blow off valve. Have a shop professionally install a complete turbo set up.
Check the thermo fuse mounted on the compressor first - it ismost likely the culprit. What causes this thermo sw to open? perhaps low gas (& oil) in the system. Or, it might be bad. To check if the thermo sw is opening, watch the A/C clutch as it goes to idle after 20 min. Also watch the A/C condenser fan- if it still runs after the clutch idles, the compressor-mounted thermo sw is opening, causing the air to go warm.
If you're talking electrically yes. Just look for a clip with 2 wires on the condenser frame and disconnect that. That will keep the condenser motor from trying to run. Just make sure you turn off your ac when you stop. It will build up too much pressure and blow your ac. When you're driving it works just fine though. I drive a 97 civic dx though. It worked on that gen.
not developing enough vacuum while driving to keep the blend door open check your vacuum lines for leaks
