Aircon is not working properly if i speed up up 100kph.

Hi.i own a galant 1990 SS. I have this problem w/ the aircon, whenever i use the aircon for about 1 hour or speed-up up to 100kph, the aircon seems to be not working properly. And it emitts fog but its not cold. I have to turn the a/c off & wait for about 10-20mins for it work properly. Afterwards the a/c will back to normal.

The evaporator is freezing up. Check to make sure it's not low on freon.

How to solve problem on 4G93 GDI,lose power went aircon is running,if u turn off the aircon while driving can feel the go fast than before,what could be the problem


I don't think you HAVE a problem. The AC system puts a significant extra load on the engine, and a slight loss of performance is normal.

best talk to an a/con technican as there is a size/capacity requirement for compressors. While it may be feasable to fit another compressor it needs matching tx valve condensor and evaporator to work properly. He should be able to tell you if it will work or not

Car jerks when I stop only when I have air conditioner on


When the aircon is switch on it puts a substantial load to the engine: you need to get your car tuned to take into account the load from the aircon. Most car have a mechanism that increases the idle speed when the aircon is active: if you are unable to get your car tuned yet, try making the engine idle speed slighty faster while you have the aircon turn-on (the ajustment screw should be close to the accelator cable connection at your engine end). Don't make the idle speed too high and check by turning the aircon off and on to assess the best compromise idle speed to stop your car from almost stalling (e.g. jerking).

Good luck!

Unwanted fumes gas in ford falcon futura


is the car on recirculate or fresh air? air from your aircon comes through the bottom of your front windscreen, make sure its clear and free of leaves or anything that can cause blockage to stop it from become damp inside the aircon ducts. if it is definately petrol fumes you may have an exhaust leaking from your engine bay, releasing the fumes into your cabin, that is the most common reason for petrol fumes in your aircon.
