SOURCE: ac reset for e320

Your Climate control unit may have to be reset. The reset works as follows: With the key in the ignition and in posistion 2 push both the defrost button and the recirc button (at the same time) for five seconds or untill the led lights in those buttons begin to flash. Wait for 30 seconds or untill the led's stop flashing. Switch off the ignition. Check the evaporator temp sensor and pressure sensor for correct functionality.

SOURCE: need ac reset for a 2003 e320 Mercedes

You could need a recharge of freon or your A/C pump is bad. You can go to your local garage and have them recharge with an aftermaket freon kit or the dealer and have them put it on an a/c machine and really diagnose the problem

If you have the hood up stand outside while someone activates your air off and on and see if the clutch on the compressor goes on and off while they activate the switch. If that isn't it the it could be improperly charged system or your climate control door that opens and closes for hot or air is not working properly and only stays on heat.

1989 buick skylark ac blows warm with new freon


My guess would be, based on the age of the car, that the compressor is out of oil; meaning it doesn't work. It's not a simple matter of adding oil like to an engine.

My ac blows warm air


You need to hook up a set of AC pressure gauges to the low side charging port and read the system pressures with the AC compressor turned on and running, it should be around 28-32 PSI. If the compressor press is correct you have some other problem like a broken air temperature control blend door inside the dash air ducting.

My 2006 impala blows air, but it is not cold at all. What could be the problem?


I would recommend that you raise the hood, locate the air conditioner compressor, turn on the ac in the car, and see if the compressor kicks on. If it does not, then you will need to have the ac charged. If it does kick on, then you need to pay attention to how it cycles, meaning kicking on/off, if it is frequently, then you need to charge it as well.

Ac/temp will not change from heat to a/c


hi you might need your AC recharging, after a time the gas from the AC tends to leak out ( as all gasses do ) you could try getting this boosted, better not say that if american might get wrong idea, maybe recharged is a better way of saying it..lol, hope this helps

Air conditioner not cooling.....


Hi!

First, I'd try checking your local Library for an AC repair manual. An Ac system has a number of different parts that all work together to cool.

That said, there are some things you can check that are easy.
First, Check the controls. Is the AC on, the blower on, and the temperature selector set on cold? Really check, because this is what is wrong about 10% of the time.

Next, with the car off, find the AC compressor. Is the belt still on it? Have someone start the car and turn the AC on while you watch the compressor. The outer part should turn, and when they turn the AC on, there should be a click, and the inner part will start to turn as the clutch engages.

Next, Look at the fans. If your car has an electric fan, it should come on when the AC has been on for while. If your car has a manual fan, then it might be the fan clutch, but there isn't an easy way to check this.

If it isn't one of the above, then you are probably out of DIY territory. Because of this car's age it probably has R-12, an older type of refrigerant that is no longer manufactured for environmental reasons. The $1100 for the compressor replacement seems high, but that should include evacuating the system and recovering the refrigerant, replacing the compressor, receiver/dryer, and expansion valve, flushing the system of the old refrigerant and oil, replacing the oil some that is r-134 compatible, and installing the updated fittings and o-rings for R-134. You can see how that adds up in terms of time and Parts.

Good luck!
