With step-by-step instructions you can do-it-yourself; if it seems too hard to tackle, then we at B&W Auto Repairs are ready to fix your A/C problem.
Warning: Be very cautious when inspecting your vehicle air conditioner, you must wear eye protection and take great precautionary measures. Air conditioner systems hold high pressure gas that when released can cause personal injury. Use all safety precautions, the refrigerant for air conditioners is very harmful and can cause damage to your skin and eyes.
Here you have a list of things to check in a DIY air conditioner inspection.
Check Drive Belts.
The drive belt is what the air conditioner uses to supply the power to rotate the compressor; if the belt fails the compressor has nothing to drive it. Inspect and schedule an appointment to replace the drive belt as needed to restore the operation of your air conditioner.
Check the Compressor Clutch.
To check the compressor clutch, you will need to turn the air conditioner on, set the air conditioner to the coldest position.
Start your vehicle and let it idle.
Find the compressor under your hood, the clutch is at the front of the compressor, make sure it is turning; if it is turning, then you have enough refrigerant, if it is not, you could be low on refrigerant. This can cause the Compressor to cycle on and off; it will also make a ticking noise.
If the Compressor Clutch is not turning, you will need to check for refrigerant leaks. Another problem may be a fuse, a wiring problem, or a compressor internal issue.
Inspect hoses for leaks.
The most common cause of an automotive air conditioner not working as intended, is from little to no refrigerant. Therefore, there must be a leak somewhere, you need to find these leaks and repair them all before recharging the air conditioner.
Leaks can be easy to find, the leaks leave behind a residue from being wet around the leak, this residue will be sticky with Freon oil and dust.
Inspect the cooling fan operation.
Electric cooling fans turn on when the air conditioner is on, if the fan or fans are not working, they will affect the efficiency of your A/C system; in fact, this may cause your A/C to not work at all.
You can find the Electric Cooling Fans on the radiator.
Vehicles without electric cooling fans use a thermal activated fan clutch which pulls air through the condenser just like an electric cooling fan; the fan clutch should be inspected as well. If this is your case, you can locate the thermal activated fan clutch on the fan blade assembly between the radiator and the engine.
