Do you mean that the AC clutch does not engage the compressor? Or do you mean that the AC compressor won't turn even if the clutch is engaged? If the compressor is siezed and will not turn even if the clutch is engaged, the only choice is to replace the compressor. If you can turn the compressor by hand (understand that the belt pulley will turn freely with the engine if the clutch isn't engaged) but the compressor clutch isn't engaging, it might just be out of refrigerant. There is a sensor, usually somewhere near the receiver/dryer) that detects the "low side" refrigerant pressure. Once the refrigerant pressure at the sensor drops below a specified level, the compressor will not turn on. In other words, if the compressor clutch won't engage it might just be out of refrigerant.
replace it, they are pretty much nonserviceable now
A blockage in the downstream side of the pump could make this pump work harder raising the amps as the pump now has to do more work to get through the line. An upstream blockage would make the pump spin more freely lowering the amps on the pump as it will not be doing any work.
The water pump uses the timing belt to spin the pulley on it. The pulley than propels the coolant throughout the engine. This keeps the cars engine at a moderate temperature.
i also had this problem and the thing that work for me was i hit the pump with a hammer, i guess it had stuck and a few tap released it straight away, you could hear the pump starting to spin and its been working since.
yes it is!! it must be froze up, the belt should turn this pulley to make the water pump work so coolant circulates in engine.
Because there is no power for the pump.
Its a Dual Pump because it contains 2 pumps, the atria and the ventricles. Atria work as a weak primer pump that pump to the ventricles and ventricles are the major pump that distributes it.
how does a rotatory pump work
yes, a watch is a compound machine because the gears in a watch that make it work are a wheel and axle because they spin in a round formation. :)
Medieval spinsters spin and arnt educated in the work that they do
shoot the watermelon and spin the wheel and win a prize is a game?
Because you are making the heart work faster,so it has to pump more blood around it.
