Heated seats turn on by themselves
Are you telling us this is a feature? Or do you have a question?
Unplug the heaters?
Possibly a feature that can be turned on and off. There’s way more complexity in cars nowadays. Check owners manual.
THANKS FOR YOUR REPLY… I AM NOW LOOKING FOR A GOOD MECHANIC who really knows the 2006 Avalanchfor a Blue Plate Special checkup as I plan to keep it a while longer.
The Avalanche is just another GM product and does not require a special mechanic . The ’ Blue Plate Special ’ sounds like an expensive sales gimmick .
