ok, after along weeknd of troubleshooting this is what i came up with with help from "xjrguy" fault test. My Ac climate control panel displays these after runnign the test:
#11: In-Car temperature Sensor? on these x300 is that the small sensor on drive side kneeboard under the smal cointray??

#23: Refrigerant Dual pressure switch:
A. refrig-low
B. refrig dual presssure swtich:
1. open circuit, high resistance or short cicuit to B+ voltage
C. high engine temperature in high amibent temperature

#32: Right fresh/Recir feedback otentiometer sensing (wiper) circuit fault
A. opencicuit, high resistance or short cicuit to b+ voltage, short circuit to grd.

You can test for this - the shop manual describes the steps required.

Same thing here - shop manual describes how to test the pressure switch. Do you have manifold gauges to test refrigerant level? It's possible, but not probable that its related to "C" - retest when ambient temps are low, like in the wee hours of the morning (reset the a/c self-test system beforehand).

Electronics are all about testing/validating the circuit - it's not a guessing game. Test the circuit - is it within spec?

caldercay, dont have manuals, idea where to get some?? I'm going to test the freon again, but geez, ijust evac and repairs, leakign service pots about 1.5 maybe 2 yrs ago, also no evidencie of oily residue aroudn anything, all looks very clean, but going to start with that, then maybe check out the 2 wire binary switch, on the ac line right before it goes into firewall... thx for all your help, will eventually get it narrowed down, slowly but surely
