HVAC control Problem stuck on

HVAC controls stuck on when key is turned off. Turn to off won't go off. Can't turn off blower. There shouldn't be power when the key is off and out of the ignition in any position correct. Is there a relay bad somewhere? If so where is it? This will run the battery down I would think. I just recently found out that when I shut the truck off I have to turn the knob to off then turn the ignition off and it will quit.......what the #&@!

I have had a similar condition for a couple years now, except my relay buzzes when the cab temp is real hot. Turn the selsctin knob, and it eventually quits.

Its porbably related to your condition.
