    default is auto lingo for ot being able to read codes, wich in your case it means the main power in the computer more than likely burnt, the inside of the computer is a board, like you would see inside any type of modern electrical componant, and it hs copper leads going to every thing, and there are sensors and chips soldered to the copper leads, if one of the leads burn, wich is common, it will cause the computer to malfunction. I hope that helps.

I have a 2003 chevy tahoe Lt the air works in front and with back controls but heat is only working in the front it blows with back controls but puts out no heat what causes this?

Your climate system can only cool or heat but not both. The temperature has a big effect on this. The cooling needs the compressor.

Airbag light stay on 2003 chevy tahoe

The air bag light will remain illuminated if a fault has been detected in the air bag system.
The onboard computer will need to be interfaced with diagnostic equipment to read the fault.
This is also the only way to reset the light.
Good luck, I hope this helped.
