Thanks Gilly, No joy on the key method and of course full power to all fuses. Its really strange, all of a sudden everything will work perfect, and when it does start to work, I cant get it to fail. The next day it does the same thing. Tonight it wouldnt come on at all, but I only drove about 4 miles. Eng temp is normal. I noticed that when system is inop the "rest" and the blue and red vent lighted buttons dont respond. So I just leave it on EC with the fan cont on hi and within 15 min or so it will come on full blast and everyone in the car says hooray!!!! Wouldnt you think that for a car costing $70,000 new, they could build a bullet proof heater? Anyway, thanks for the imput, if you think of anything else let me know, Im going out to fool with it some more
