Question about 2002 Chevrolet S-10
The air conditioning compressor will not start thus resulting in no cold air into vehicle. What is the probable cause of the compressor not coming on. Thanks
Most likely the cause is low freon charge. Contrary to popular belief, an A/C system never 'loses' freon normally - this always means a leak but sometimes the leak can be so small that it is virtually undetectable.
Your A/C system has a 'low pressure' switch, usually mounted on the compressor, that shuts the compressor down to prevent damage when the freon's psi falls too low. To test your compessor: with the engine running you'll need to connect a wire to the positive battery terminal and one side of the switch and just touch another wire from the negative battery terminal to the other side.
If the compressor is OK, the clutch 'plate' will engage & spin when both wires are connected. Either way, you should have this done at a licensed garage as you probably don't have the proper tool to test & repair the system if you do find the problem.
If you decide to do this yourself, please be very, very careful not to get shocked (use thick wires with good insulation) and don't wear long sleeves or loose clothing as you will be working right near the spinning pulleys and belt(s). Good Luck!
