    Weirdest thing happening in my 2007 EL Limited. When I hit the brake, it will cause the heating and cooling fan to momentarily go up to a high speed. After a few seconds, it comes back down. Sometimes, when it stays that way, I can cycle through the controls and get it straight, but, sometimes when I hit the "OFF" button it causes the fan to up to hiogh and stay there and none of the speed controls work, on the dash or on the steering wheel. Today, it happened again and nothing is resetting the speed of the fan to a lower setting. Even after turning off the truck and letting it sit, the fan will be on the highest speed continually. I can re-direct the vents and temp. Just the fan is stuck on high now. What gives??!!!
