Car A/C comes on but won't stay on, what's wrong?

Question

Does anyone know what could be wrong? The AC blows coldbut won't stay on. The light shuts off on the AC button, but everytime you push it, it will come back on, but then it goes off again.

Thank you Will S. for your earlier advice.

Answer 1

Could be you cycling switch,due to low freon,does your car blow cold or mediocre.i would check your level with a pressure tester to if you need to add some mor freon,you can buy a can with tester at most auto parts stores....

Answer 2

Normally this is caused by a low refrigerant level. Have it checked at a local shop and refrigerant added if necessary.

You can also purchase a kit at Wall-mart and other places also.

Answer 3

high pressure switch you have a plug get it checked

Answer 4

It could just be the wire behind the button is loose or starting to short, because you said when you push on it again after turning it on, it goes on...i would look at that first before you get into pricier alternatives..good luck!

Answer 5

Welcome. It could be that your expansion valve or orfice tube is clogged or your pressures are irregular causing it to shut down.
