compressor issues?
lately I've noticed that when I have my heat on, my compressor will click on and off.... sometimes every 5-10 seconds continuously. when it does this it make the whole truck move a little bit.... is the compressor going on the truck or is this some other issue? also isn't the compressor only suppose to click on when I'm using the ac?

Does the idle go crazy for a second every time your compressor kicks off? Does it stop if you set your a/c to off or dash vent? I just had this happen a few months ago.
Your a/c refrigerant is a little low and it causes your compressor to kick off abruptly. Remember that your a/c is on with every setting except the dash vent setting. Just go down to the auto parts store and get a small can of refrigerant (R134a). Its and easy fix and not a big deal, if you haven't been using your a/c for a while the seals can get dry and leak a bit.

AC refrigerants tend to slowly leak past seals as well as permeate through system components such as flexible lines. Since your truck is about 9 years old and if the systems has never been serviced its probably running low.

I added some yesterday and my gauge was reading past 50 psi (just before the warning section)... the temp outside was like 30 degrees. everything seemed fine. I even checked the gauge with the truck off to and it gave me the same reading. I notice when I have the gauge on it the psi's fluctuate back and forth as the compressor goes on and on, sometimes even going below 20psi (low) and then back up eventually just past 50. when the gauge fluctuates does this mean it's going through its cycle? also when it goes back 20 psi's for moment then when the compressor comes back on does that mean it's satisfied?

In order to accomplish this you'll need to temporally by-pass the low pressure cut off switch (cycling switch). You can do this by removing the electrical connector at the accumulator and inserting a wire jumper in the connector. This will allow the compressor to stay engaged.
Now read the gauge. If its below 25 psi you’ll need to add more. To do this hold the can in the horizontal position. Using both hands to help keep the can warm, open the valve and slowly rock and tip the can side to side so your adding liquid when the can is tipped towards the gauge side.
Once it gets in the range of 25-30 psi close off the valve and let it run for a few minutes. If the gauge goes back down, open the valve and add some more until it stays steady.
Turn of the engine, remove the jumper wire and reconnect the cycling switch. Start up the truck and see if it works normally now.

So now I started filling it.. the compressor isn't turning and the pressure on the LOW side was at 90 psi... so I started to let tehe air out since I guess I overcharged it. Now the high side is at like 50psi and the low side is at around 30 and the temp inside the cabin blowing out is 110 degrees..
What did I do wrong. Should I just completely drain the system and then start again?
This can't be this hard and I f'ed it up...
Please help :-(
Thanks,

So I completely emptied the entire system and now I am vaccuuming the entire system out... it's at -30 psi on the LOW side now...
What is this on the gauges:
When I unscrew or tighten this down nothing happens.. is something supposed to happen. When the valves opend I can completely unscrew this and nothing comes out...
