Perhaps the blower motor resister for the fan not working in first two postions and a drop of oil on the motor shaft? Is any of this halfway easy to get to?

When the truck is in park it doesn't have a constant idle, rpm's lower almost to zero before going back to normal. When truck is about to stall tha battery guage halls off to the left slowly sort of ... Read More
