I had the same problem we had put a new motor in our van and the lights kept flashing. I ran the test with the rear wiper buttons but the ac light kept on flashing. After we fixed the ac I ran the test again no success. I ran the cool down test with slides to the right, they were still flashing ( it actually wouldn't even run the test). I ran the test with the slides to the left and SUCCESS. Finally after months of those annoying lights my van is one step closer to being back to normal. Thanks for all your different ideas. Tom
