Well I got my tahoe put back together

[blizz]

With the winter and what not, I had put this thing on hold but I finally have it all back together after putting all of the AC parts in, new lights and a new stereo. She fired right up but I did hear a little squealing at the compressor. It kinda sounds like the belt is maybe sliding on the pulley. Any way to resolve that? Also, on the dryer, is there a port that's not used? I didn't have anything to connect to it so I'm not sure. I took this thing apart about 7 months ago so I don't remember lol. I also have this extra plug that I'm not sure where it goes. Any ideas?

That port on the canister appears to be one of the 2 ports for testing and filling the system. There should be a hi side and a low side port. I dont mess with a/cs too often so not sure which is which. Also on a side note when i tear something down especially electronics i always mark them with something. Peace of mind when im done and i have that extra connection i know it doesnt go anywhere.

that should be a cycling switch that mounts there. and the test ports should be on the compressor lines mounting blocks.

I was wrong i forgot about the cycling switch. Thanks for the correction sunlit. I even had to change that on my suburban i used to have and i still forgot about it.

I looked on the old drier and there's nothing on it just. Hmm maybe I took it off time to go rummaging.

blitz, #28 and 29. and you do need it other wise the unit will not operate correctly like freezing up or just draining engine power.
