Hello, I am Danny.

You will need to have the codes rechecked. All codes begin with a letter for example P-Powertrain, B-Body, T-Transmission and then have 4 numerals- Example Code P0405. If you do not have access to a code reader/scanner your local auto parts stores(AutoZone,Pep Boys,O'Reilly's) will do it for free. I have attached a tutorial showing what is involved. Get back to us with the code(s) and we will be happy to assist you. Hope this helps and thanks for using 2CarPros.

Hi Danny. Thanks. I should have mentioned that code 31 was from the heater self diagnose, not from a OBD.
