Help me help my brother-in-law
My brother-in-law called me to see if I wanted to make some money changing the A/C compressor on his 2000 Xterra. I asked him why and he said he thinks it locked up, cause all of a sudden a belt started squealing and smelled like burned rubber... So I take a ride to his place and look at the beast before he gets home, and the belt is chewed up pretty good, but I can't tell much from just looking. So he gets home and fires it up without the compressor on, then I have him turn it on, and the clutch doesn't engage.
I can't tell if the compressor is locked up, cause the clutch wouldn't engage, and I'm wondering why. I could turn the clutch from the front of the pulley by hand, but I don't know whether or not that was actually turning the compressor. I didn't have my gauges with me, so I couldn't check to see if he had sufficient R-134a. I've been told before that if the system doesn't have enough refrigerant that the compressor won't turn on, or something to that effect. Anyone have any insight? I know you Cali guys like to just take out your A/C and all (lol), but I'm sure someone has some pointers... Thanks

if there is too little or too much pressure the compressor wont turn on
when you turn the clutch by hand, you are not turning the compressor. just the clutch basically, when you turn on the a/c, voltage goes through it and magnetizes the compressor which moves the clutch and engages it. so give the compressor direct 12v and see if the clutch catches |

That's gay. That connector is a total pain in the ass to get to. Oh well, we'll try it.
You say if the pressure is too low it may not turn on? Cause my sister was complaining that the A/C didn't get cold enough. EDIT: Talked to him on the phone, and he said it may have too much pressure, cause they thought it may be low so they put some more in it, and the gauge read that its overcharged. Overcharging can have serious consequences, right?

in that situation, probably low pressure, so the a/c wont actually turn it on. So check the freon levels.
