Hating my sho right now

[d2freak82]

2 months ago or so I put a frickin used ac compressor in... charged the system, found out I had a leak so I waited until I could get a hose. Which was today... I installed the hose, vacuumed down the system, and guess what... damn compressor won't kick on, I checked the fuse under the dash and the one under the hood.
I'm so mad, I was so excited to get my ac back.... any ideas whats wrong with it? the clutch turns fine.

2 things.

First is that the low pressure cutoff switch could be bad, you could temporarily jumper it and see if the compressor kicks on.

second, the compressor clutch could be miss-shimmed. if the jumper thing doesnt work, tap on the compressor clutch when the car running and the ac on. If it kicks on it's not shimmed right.

There's a how-to here somewhere about shimming.

if there's not enough freon in the system it won't come on? Because I just vacuum'd it down I haven't pumped anything into yet. Maybe It just needs some freon? You say low pressure switch is why I mentioned that.... assuming that there's not enough =)

it wont come on until its part charged

holy crap I feel like a tard... I didn't know that. It works great now! I just didnt' want to pump any freon in if it didn't work

The blower doesn't seem to blow much for being on high... Maybe this is normal but anyone had a similar problem? Maybe i need a new blower motor?

you ever find out if you have to pull the dash to get all that out?

No, just remove the glove box and the blower and you can see the evaporator.
