Well fellas, I did not replace the dryer or the o-tube. I vacummed it last night got it to 30 mm of Hg, not sure of units, but gauge was almost pegged. Checked it again this morning. Still had same reading. I installed about 2oz of oil on the low side by pressurized can with the engine not running. It was a 3oz can but i'm assuming the pressure equalized and that's all I was going to get in.
Then I added my 850 grams of R134. It is cooling now. Not sure what the temp is supposed to be at the vent. I got 54 deg F with my cheap multimeter and about 63 deg F with my analog thermometer, both readings at idle. That is with no recirc flap. I pulled it since it had broken off.
The initial problem I had was that the clutch would not stay engaged. It would try to kick in 3 times that just stay off. I direct wired the compressor and it would cool and work fine. For this reason, I chased other things. I replaced the control head thinking it had to be a switch problem. That did not work. Then I changed the high pressure switch thinking it might be faulty, and that did not work. Previous to changing out these parts, I had taken the truck to an "AC specialist" he told me it had plenty of freon and that, that was not the issue.
So finally I replaced the compressor even though it did not make sense, same as 1Ton, Fire Medic, and Nav Man, all here on this forum. And that did the trick. Thanks guys, I appreciate your input. Next time, I will replace the dryer and orifice tube. You had good points on why these should be replaced. Right now, i'm out of work so, if this gets me by, then I will take it. Trying to conserve cash where I can. Thanks. :-)
