1984 Vanagon with "power nothing"
   My blower motor works *sometimes*.  I've not been able to get it to even
twitch, fiddling with the switch, but then later, it does come on like it
should,occasionally, when I turn the switch...then it'll quit if I change
speeds.
   Is there anything I can get to, besides the fuse, without removing the
whole dash?
   at the same time, my gas gauge and water temperature gauges sometimes
read very wrong... Low...but usually function normally...related? these two
electrical glitches?   thanks
