green. At that point the truck stalled.
Thanks

Find you a friend or a trust worth mech that can work on A/C's and do
not waste time (or money) with diagnosis and have them replace the
compressor, the expansion valve/orifice (because it has a screen that
can be trashed full from a compressor failure) and the receiver/dryer
assembly (because you should always replace them with a compressor
change). Add correct amount of oil (parts will come with instructions to
the effect for mechs) and vacum down system and install R134a and you
should be as good as new.

Would be funny if he did all of this and it was just a bad cycling
switch....

Not as funny as believing the compressor is okay and trying to fix it with a switch. I guess you have never seen one locked up, I have seen more than a few in my lifetime american and foriegn.

He was never really clear on if it was locked up...For someone to even
say its locked up and knows about HVAC first without pressure readings
also without on this one bypassing
the cycling switch to make sure the compressor has power...Is basically
a backyard mechanic trying to make a guess....I dont know how many times
Ive seen people say they needed a compressr and it was a 25.00
Switch.... As far as we know he clutch plate could be loose which will
do the same thing....Then what change the compressor no you change the
clutch....Just too many parts changers anymore and not enough good
mechanics... >> Stay informed about: 2000 Silverado AC |

If you read his earlier post you would see that he said that the engine would stall out and compressor not trun when he jumpered comperssor on line manually. This is not a charge issue as I have seen this before. I have seen them lock up on the road and throw, smoke or tear off belts in the process. They can sieze very tight sometimes. >> Stay informed about: 2000 Silverado AC |

I did exactly this on my 89 S10 Blazer. 4.3, 4X4, 700R4.
Afterwards, the compressor made a rattling noise. Nothing is loose, all
tensioners on the engine are in good shape.
Compressor came with a clutch on it, and a warranty. Warranted it out,
replaced it. Same damn thing.
Any ideas? >> Stay informed about: 2000 Silverado AC |

BTW- added GM-type PAG oil each time, directly to the compressor, first
thing. also, the noise goes away when I turn the AC off. When I turn it
on from a cold start, it's quite the first couple seconds, then starts
making noise.
With a full charge of 134a <reading 35 PSI while compressor runs, at
80deg ambient temp>, it blows 46 degree air.
Any more info you need, let me know. Much appreciated! >> Stay informed about: 2000 Silverado AC |

perhaps the truck isn't idling-up enough to compensate for the
increased drag of the compressor?
IE: perhaps the compressor is fine. Maybe the ECU has a problem? |
Yeah right with a V8 too!!! You are reaching for something not there. BTW the idle control circuit in a injected engine would adjust idle anyway, even on a 4 banger unless it cannot idle because it is locked up that is.

Maybe in some trucks but it can be for 25 to 50 PSI depending on tempature and humidity because humidity can have a BIG effect on outlet temp and pressure. (under low humidity the air will be colder and pressure lower to and under high humidity, air will be warmer and pressure a lot higher too so one day it might be 35psi and 46 and another day 55 and 45PSI. (may truck runs 25 to 30 PSI on lower 80's with some humidity and my wifes 20 to 25 PSI and hers is cold too) It is not set in stone and you have to look at high and low side to really judge how it is working in a specific tempature and humidty.

hm.. good point.
Unless the idle control system was FUBAR, too, like in a bad ECU? 
Please take a look at my problem elsewhere inthis thread, and tel me
how to test this sucker properly? I'm particularly concerned about the
rattling noise both compressors have made.
How's the OP coming with this problem? >> Stay informed about: 2000 Silverado AC |
