Mr. Dalton,
I did not mention in the 1st email, that I checked power on Yellow at the regulator. There was no power. That's why I removed the regulator. And, I thought Auxillary Fan was for the fans in front of the radiator. Since the fuse was blown, I just replaced it. I had replaced the fuse (not OEM) and I frequently checked power at both sides of this fuse. If there was a break in the fuse, I still should be able to detect power coming in, shouldn't I? But, there was a time that there was no power at both sides of the fuse. Funny thing is that when I replaced the fuse for the auxillary fan, I got power at both sides of the fuse. Mr. Dalton, what is the chance of having the bad push button switches? How do I check if I have a good/bad push button switches?
