This system has a h t 6 ac compressor that is most likely the problem,replacing it is the best thing to do if the leak is often,and this ac compressor is at the top of the line for problems with leaking,stop leak will not work,and if the leak does not occur very often,just recharge the system,but if it is often,replace the ac compressor and it`s components.If this was at all helpful,please rate,and thank you,and buy the way ,it is a 99.9 percent chance ,this is the problem,

97 Grand am v6 up & down idle. Driving =steady acceleration. I've changed, O2 sensor, throttle positioning sensor. Scan is still saying Random misfires? Get warm won't start.


P0300 Random misfire - lean condition , vacuum leak , low fuel pressure , fuel filter plugged partially , mass air flow sensor .
If the misfire is random, check for the following conditions:
?€¢
System Grounds: Ensure all connections are clean and properly tightened.


?€¢
MAF: A Mass Air Flow (MAF) sensor output that causes the PCM to sense a lower than normal air flow will cause a lean condition.


?€¢
Air Induction System: Air leaks into the induction system which bypass the MAF sensor will cause a lean condition. Check for disconnected or damaged vacuum hoses, incorrectly installed or faulty crankcase ventilation valve, or for vacuum leaks at the throttle body, EGR valve, and intake manifold mounting surfaces.


?€¢
Fuel Pressure: Perform a fuel system pressure test. A faulty fuel pump, plugged filter, or faulty fuel system pressure regulator will contribute to a lean condition.


?€¢
Injector(s): Perform injector coil/balance test to locate faulty injector(s) contributing to a lean or flooding condition. In addition to the above test, check the condition of the injector O rings.


?€¢
EGR: Check for leaking valve, adapter, or feed pipes which will contribute to a lean condition or excessive EGR flow.

Reviewing the Fail Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.

Why is my Air conditioning compressor cycling on and off?


Likely, you've lost your freon due to a leak. If the leak is slow, you can add a leak sealant and more freon yourself. If it's a major leak, that will work for a few days, and then all leak out.

Air condition


If you've never worked on an air conditioning system before, I would recommend you take it to a shop and get it checked out.
If the system is low on freon, you have a leak that would need to be fixed to keep any freon you add from leaking back out. And it could have an electrical problem instead of being low on freon.
Freon gas is minus 35 degrees when it comes out of the can.

I have a 1999 323i BMW. The AC doesnt blow cold (on cool days it blows cool temperature but not common A/C Cold Air, Hot Days it blows Warm/Hot Air). The heater blows warm air but definitely not common...


First things first.....You must have the air conditioning system hooked up to an a/c system machine and then checked for leaks and also read low and high side pressures. If there are leaks then low Freon (R134a) content and low refrigerant oil can cause the a/c system to not engage the a/c compressor which basically means you will not have proper defrost functionality nor regular air conditioning. Most shops, when working with your air conditioning, will install air conditioning dye to assist them in locating leaks and is the first step in diagnosing all a/c systems. Post the findings after thw

I have a 1992 mercedes 200 E WDB 021 Saloon, it has 8 button air condition and I dont know how to use it. Control wheel on blue position but When I push the button (leftmost)which has a glass figure on it,...


The pulley on the air condition has to turn it has a belt on it. The Compressor engages to pre cool the evaporator. Most likely you have a blend door pod leak or leak in the hose or the sampler valve is bad. I would replace the sampling valve behind the glove box/air bag. As that reads the cabin temp and if it thinks the car is cold the heat will stay on because everything is automatic. All vents will blow cold when it thinks its hot and in addition to floor and corner dash center vents will blow cold when it works. If the direction of air is correct then the A/C system may have a leak or need a charge of freon.

Air conditioning is bad


Early use of the new type freon - kills those old seals quickly.
You may have a cracked O ring seal in the high pressure side of your air conditioning system. Have it checked with a leak detector... that should tell which seal is leaking.
