SL/R230: A/C low performance, star readings included




As far as I can tell all the readings look good except the Evaporator Temp at 73F, on an earlier reading is was at 66F.
For a little history, the wife and I took a 6k mile roadtrip across the country, on the last day the A/C OFF light came on and couldn't get it working again.
When we got home I reset everything with star and it worked fine after that. A few weeks later it started blowing not so cold anymore.
Any thoughts what it might be?
This is the screen before you do a diag test. It has you check the resistance of the evaporator sensor next, but I stopped there for now.
