So, yesterday my 2006 "garage queen" Silverado did something new. I warmed up the truck, turned on the heat and drove a few miles with the heat working. I noticed I was getting cold air out of the driver side vents after about 5 miles, its equipped with the dual zone temperatures. well the passenger side worked correctly however the driver side blew out cold air. I turned the heat off/on several times with no good results. after I made a stop and restarted the truck after a few hours it was working as it should again. this is the first time this has ever happened. extremely well maintained/over maintained truck. 92,xxx on the clock. any ideas ?
Also on a side note.. likely unrelated, the battery gauge on my truck usually reads right about/above 14 and the battery is 2 years old. I hook up a trickle charger about once a month to keep the "garage queen" topped up on juice.. I have noticed the last two outings in the truck that the gauge has been reading at a higher level than usual. even after 20+ minutes of running.. I can account for a higher read as its topping the battery up after sitting for some time. Ive owned the truck since 2006, second owner and like to think I know its behavior fairly well.
again, ideas ?
