Auto Ac Troubleshooting

Unusual situations are amassed frustrating than when you turn the air conditioning on in your van in the Centre of a 90-degree generation and treasure that it won't blow gone any bloodless air.The air conditioning vents are controlled by an electrical servo, vacuum servo or cable. Warm air will come out of the vents from the heater if the temperature blend door will not work. To check if this is the case, start the engine and let it idle, then set the blower dial on the lowest setting and switch from warm air to cold air while listening closely to the sound from the vents.



The drive belt is what causes the compressor to rotate. The compressor is very much like a refrigerator pump. If the drive belt is not working, the compressor does not have anything to make it go. If the drive belt is worn, replace it.


Examine the Compressor/Clutch Connection


Turn the air conditioner control to the coldest position, and allow the engine to idle. Look under the hood of the car and check that the clutch on the compressor front is turning. If it is, then the air conditioner has the refrigerant necessary to work. If not, you will need to purchase a recharge kit to recharge the air conditioner; be sure to reference the year and model of your car in determining which refrigerant to buy. If the air conditioner has some refrigerant but not a high enough level, the system will cycle off and on and make a clicking noise.


Check for Leaking Refrigerant


If the clutch on the compressor is not turning, you should check for a refrigerant leak. If there is a leak in the air conditioning system and the refrigerant will not stay in, the air conditioner cannot activate. You will need a refrigerant leak detector to determine if there is a leak. In the absence of a leak detector, look outside the system for an oily residue on the compressor, evaporator, condenser, and on all the hoses.


Examine Fuses


Examine the fuses that are located under the dashboard panel, and replace any blown fuses. If a new fuse will not work, then you might have a short circuit in the system and may want to have the car serviced.


Examine Temperature Control Vents


Decent thanks to the air isn't chilled doesn't scrimpy the air conditioner is completetly kaput, on the other hand you cook commitment to inspect the transaction to cinch what is causing the failure.

Examine the Drive Belts

Whether the air conditioner is not cooling the machine, look the drive belt. You should hear the door opening and closing inside the heater box. If you cannot hear this, then check in the servo for a shorted motor or for a vacuum leak. Replace the motor or repair the leak.
