I'll start with an apology if this question has been asked before, I have done a search but couldn't find any similar problems. I have a 2001 Rav4 that recently has begun acting odd. Up to now it has operated reliably with very little issues. It has about 170,000 miles on it. Recently when I would turn the key to try and start it there would be no power at all. No lights on the dash, or dome light, nothing. I have had the battery checked at two locations and it's fine, the terminals have been cleaned and tightened. When I would watch the dash board I saw the temp needle jump a little. Then if I would leave it alone for a while it would start just like normal. Any suggestions would be great.
