    Hold down the OFF and WARMER buttons on the climate panel until all the dash lights come on. Be ready with a pen and paper to write down the codes that come up. They will look something like P048 or p013. Write them all down. When you see "PCM?" press the OFF button about 4 or 5 times until the dash goes back to normal. If you missed one of the codes, do the same thing again and the codes will still be there. Once you get them all, post them here and somebody will tell you what they mean and what needs to be done to fix it.

    Good luck...
