2010 Vauxhall Astra H (1.4 sxi) Air con previously not working. Had car re-gassed, still no joy. In Opcom Aircon was set to not activated. Changed this to "with clutch setting" an Aircon working now:-) ...

air cont flow sensor may have failed cannot remember on 1.4 model but on 2.0 model its on the left side of the engine. it could be this. a/c dont usually have codes to store. accelerator code is the sensor on the intake on the side. prob just needs cleaning mark were it fits with a pen and take off. on op side there is a hole spray some wd40 in the hole cover it and shack it around . then tip out and leave to dry. then put back on. should be fine then.

Fault code P2106

is it the ecotec engine fitted 1.8 or 2.0./2.2l or the diesel 1.7 engine.. how long have you not used the air con for. not using it for a long time you can damage the pump the flown sensor. even the temperature sensor. but if the engine is trying to stall with the ac on then the pump may have a fault. ac should be run for 10min once a week no matter the weather. stops you having problems later.

Your not going to like this but that is either a water pump being out or cracked cylinder or blown head gasket.

My fans are not comming on untill the temputare reaches 226 dreegs can you tell me if there is another sensor beside the 1 on top if the moter or the computer

there is no other sensor, that is probably how it is supposed to work-it goes on at 226 and off at around 205-I have a 2001 aurora and 2000 intrigue (GM) and they both do that too, correct according to the field service manuals.

The a/c on my 2003 honda accord will all of a sudden stop blowing cold air. I already had the filter changed thinking that was the problem. The mechanic is having a hard time figuring out what is wrong...

have you tried refilling the aircon gas ?

It goes empty after a while.

The reason for cold then not cold is because it is a system that works in reverse of your radiator.

The gas cycle through the system. goes through the radiator of the the aircon system (not the same as the one for the engine). there is extracts the heat out of the air. the air is now cold and pushed into the car.

the warm aircon gas the made cold further along the system but the dont have enough in the system.

imagine athletic ruynning around a track. all 20 are bunched up together. there is w spot light in the centre of the infield shining on you.

the track is your aircon system.
the spot light the air coming into your car.
You are the car
The athletes are the aircon gas.

When they run between you and the light the air is cooled off and you are getting cold air.
now of goes the air (athletes) around the system and till they come along again you get hot air.

Now fill up the aircon system (put more runner on the track and voila, less light reached you cos there is more gas in the system.

However if you refill it and after a day or even just a week it the same again you have a leak in your system and will need to have it looked at by someone specializing in car aircon repairs.

E180auto passengerside aircon always blowing cold 1992 model

Sounds like the vent control motor is bad. It controls how much hot water flows through the heater core. OR the heater core for that side is clogged

Car overheats

Look in your manual and see if you have air bleeds for the cooling system. Pressure test the system, and remember to have heater on HIGH during filling and testing.

The pressure test will help you to know if you have much air in the system.

You did not mention if the FANS are coming on, I presume so, but if not, resolve that issue, typically a heat sensor.....

If you find no leaks and not much air in the system, get vehicle hot, by driving, shut down and feel around on the radiator, if you have cooler spots, it may have restricted portions. If so, replace it, do not waste time repairing it....

Lancer 94 el vibration when aircon is ON

ASE mechanic:
Sounds like you need to check for loose belts and or pulleys. and or maybe the A/C compressor mounting bolts are loose. in all extreme measures the cycling clutch could be going bad, and motor mounts still can solve problem
