Where is the code on an 04? Just bought a used 04 yesterday and the (chevy) dealer I got it from did not know the code. I looked under the emergency brake and did not see a white box with code number on it.
I also looked behind the glove box and saw nothing....
On the 04, it's on the passenger side, above the fuse box. You have to remove the fuse panel cover and look straight up under the far right side of the dash. The controller box is under there, but the sticker is hard to see. You really have to get way up under there to see the code.
I notice your in Maryland, do you have a good mechanic? I have a plowing business and need to have some things added to my new truck.
Plow mount, aux fuel tank,light bar, headache rack, flashers for taillights, back up lights. Things like that. I've also gome some 2 way radio equipment I'd like to have installed and upgrade the stereo.
