Went to a wedding reception today, a two-hour drive to Indianapolis from home here in Illinois. On my way home, with less than an hour to go, all of the sudden the dash went mostly dead, the Cruise Control was dead, and the HVAC quit blowing the much needed cool air in my face. It was friggin' hot, which may have contributed to the issue.
I had my GPS to give me a speed and my Hellroaring charge indicator was still glowing bright red. I had power for many things like the audio from the head unit, the cigarette lighter circuit was OK (GPS was running off that), and my Scangauge gave me the all important water temp. I decided to just keep going.
I cracked my handy EWD open. Sure enough, the Gauge circuit fuse was blown. I replaced it and fired the truck up. Gauges were back, but so was the AC, to my delight (after imagining how much it might cost to fix that.) Sure enough, the Power Source (Current Flow Chart) on page 42-43 shows that the Gauge circuit has as "Related Circuits" the AC, the blower, cruise control, and things like lockers (which I don't have) all seem to have some connections with the Gauge circuit. Never would have thought most of those would have a connection to the combo meter circuit with the gauge cluster on it. This does explain how I was able to continue home, although it was getting pretty hot without the blower running.
My question would be, after replacing the fuse and getting things going again, Is there anything else I should run down as a potential problem here? I had just turned the blower on its highest setting shortly before things went off, so maybe that extra little bit of power was enough to blow the fuse. Never had a previous problem with the blower, so maybe it's just getting old, a little more drag and higher resistance and the fuse blows. Looks like I will have more opportunity to test this. However, any thoughts on this would be appreciated.
