My 'auto lamp' headlights stayed on all the time and the A/C started to cycle off intermittently, worked fine when it ran. I did an EATC test and it gave a 050-053 code,which means the sunload sensor was the cause of both problems. You have to lift the decorative deforst grill,it's clipped in pretty good, but pulls up eventually,working from one end to the othe. Unplug the sensor , remove and replace sensor in cover and reinstall. Everything is back to normal. Cost $50,this is only a dealer item,which they had in stock.
