Possibly due to a failing compressor. The A/C compressor in vehicles has a clutch in it which operates by friction. If the bearings are going bad, or the clutch is about to lock up, it can overload the engine as it tries to spin the compressor. The excess load on the engine makes the engine want to slow down, but the engine is designed to compensate by trying to speed itself up to normal operating RPMs and thus continue running unless the starter switch is set to the off position. This battle can result in jerky motion from the engine, which is tied to the frame of the car by motor mounts, as well as the transmission to the wheels. If the car is in park or neutral, the jerking motion is transferred through the motor mounts to the car frame. If in gear, it is transferred through both the motor mounts and to the wheels through the transmission.
because when your driving, air goes up under the car. And since a car has a frame, air hits it really hard causing it to shake. example, planes offend have turbulence. its because air is going under the wings the wrong way and making it lose balance and shake. Same thing as the car except its not a plane.
It depends on the type of car, the age of the car, the condition and up-keep condition of the car and also how cold it is.
You cannot turn it on because it cannot be turned off in a car. It is always on. In some 2 door trucks you can turn the passenger air bag off/on, but not in a car.
no
yes
This may be a misfire caused by a low fuel pressure.
The right hand side fan is for the air condition. If the car is on and you switch the air condition the fan will come on.
Your car fan turns on when you have your air condition unit on because, your engine heats up more when the air is on so the fan needs to come on to cool the engine down.
Tires need balancing.
It depends on your car, cars generally have a dial on the dash board it will have a picture of a blue fan or a red fan, Turn it towards the blue fan that blows out cold air. P.S that's how they are in most British manual cars, if it's not that sort of car then I don't have a clue, sorry.
in 1930 was a ford truck
no, it just uses your car battery
