Have a 93 gsr. Want to recharge my ac but want to make sure my compressor is working. Should you hear a noticeable sound when the compressor kicks in. I have the ac on blast but notice nothing. I’ve got the hood popped open while doing this. Also, the blue light on the ac button doesn’t come on. Can that have something to do wit it or just a bad bulb. All the other lights around there work and everything else on my ac/heater/blower work.
you should be able to see the clutch kick on and off which is directly on the front of copressor where the pulley is if not visible there should be a click sound every so often like a couple minutes apart even less most importantly is the air blowing cold.
if theres no refrigerant in the system alkready it wont kick on, it has a low pressure cut out to prevent damage to the compressor by running it dry
You can use a jumper wire to check if the compressor works
