Hi, I have the ERA 70A also. I have a question for you. Have you run the A/C and or heat strip? I was in Scottsdale a couple of weeks ago and the temps ranged for low 50s to high 80's. The heat strip on the A/C would blow mildly warm air but not heat the interior much. I traded in an Aspect and the heat strip worked great. And the the second thing is that the A/C if pushed all the way to the edge of the blue(coldest setting) would seem to quit working, too. If I back it off a notch, it seemed to work better. Have you experienced this? I was wondering if I need to have it checked.
