Someone posted a possible solution on here - and it seems to have worked for me! Steve said to:
1. Have both temp controls all the way over to cold
2. Start the vehicle
3. In unison, rotate the temp knobs all the way to heat, back to cold, repeat 3 times. Seems to have fixed it! (??) He actually suggested disconnecting the battery for a short while first to erase memory, I didn't even do that part. Just spent $350 last week for bad O2 sensor (wires were chewed by rodents) so I was glad not to be faced with another repair bill!
