ac blows hot fix
by: Jshowtime

I have had the same problem and there is a simple fix.it is correct to say the diverted gets out of sync. There's a fuse for the ac under the passenger side floor.remove the fuse. Turn the ignition on so it registers in the computer then turn it off. Replace the fuse.turn the car on then wait 5 to 10 minutes for the computer to reset the diverters.sometimes it take a couple times for it to resync.
