Question about 2004 Oldsmobile Bravada
One side blows cold air and the other side warm air. I assume the Control Blend Door is stuck. Everything was working great until I replaced the battery. I have disconnected the battery and after waiting for 30 or so minutes, reconnected the battery with no change. I also tried taking our the HVAC fuse B and waiting then reinstalling with no change.
Surely, replacing the battery didn't not ruin this door. The dealer is asking $700 bucks to repair. I think the DTC need to be reset.
Any ideas how to repair?
You might try treating it like a computer...reboot. Disconnect the battery for 20 minutes and make sure the cell phone charger doesn't have a cell phone in it. Surprisingly enough, there was a guy years ago on the old Wrenchead.com site who couldn't reset the codes on an OBDI vehicle and later found a cell phone on the charger which was back feeding the ECM enough the codes wouldn't reset.
dont rate it until satisfied
