Why does my car idle rough when i turn on the ac




Many factors can cause your car to idle rough when you turn on the AC. One possible reason is that the AC unit is putting a strain on the engine, which causes it to run less efficiently. Additionally, turning on the AC can also cause your car to use more fuel, which may result in a rough idle. If your car has a manual transmission, you may also experience a rough idle when the AC is turned on, as the extra load on the engine can make it more difficult to shift gears. If you notice that your car idles rough when you turn on the AC, be sure to have it checked out by a mechanic to determine the root cause of the problem.

Why is my car smoking under the hood ?

If you're experiencing a rough idle when you turn on the AC in your car, there are a few things you can do to troubleshoot the issue. First, be sure that your AC unit is actually working properly - if it's not blowing cold air, that may be why your car is idling roughly. Additionally, make sure that all of your car's filters are clean and in good condition, as a dirty filter can affect the way your car runs. If you've ruled out these potential causes and your car is still idling roughly when the AC is turned on, it's likely that there's something wrong with the engine and you'll need to take it to a mechanic for diagnosis and repair.

Prevention :-


If your AC unit is turning on and blowing cold air, make sure that you check the cabin filter. This can be found under the glove compartment of most cars. You may need to remove the glove compartment or disconnect a battery cable before you can access it. Once you've checked it and determined that there isn't any dirt or debris preventing it from working properly, turn off the AC and restart the car (if it was running). If your car idles smoothly, then you know that something inside your engine is preventing your AC unit from operating correctly. If your car still idles roughly, take it to a mechanic for repairs as soon as possible so you don't damage anything else in addition to what's already been done!
