The sensor is on the high side line someplace. AC Delco part number 1551343
Again, a Mitchell subscription can be a big help. You can screen shot the wiring diagrams & save them, that alone is worth the $20 charge

I've tried 2 remanufactured compressors and one labeled NEW, all same results. I put a new scroll valve in the initial compressor hoping that was the issue, no dice.

Changed out the highside switch, no change. If I hold the throttle down at 1500rpm, temp immediately drops, I let off temp immediately goes back up. Any other ideas?

That's opposite of what you say in your title.

Do you typically only read thread titles?

My apologies for the misleading thread title. I don't see an option to change the title. I'll see if I can get a mod to adjust it.

No but the facts stated here are contradictory. Regardless, if there is normal cooling at above idle that drops to little or no cooling at idle speed, it points to a bad control valve in the compressor. Or at least it has on 3 of my last Vues in which I replaced the valve.

New control/scroll valve was the first thing I did, didnt help.
