    P0135 B1S1

    2006 5.3, 229k miles, upstream O2 sensor heater circuit problem. I replaced the sensor, same problem. I rang the heater circuit wires in the sensor I took out and they were not open, which is I think the typical mode of failure. Fuse is good and if it weren’t, B2S1 would have the same failure. I...

    '02 Tahoe rear heat/air no blow

    I've googled and searched here and don't see a problem like mine. My Tahoe has hvac controls above the rear view mirror that I suspect are supposed to make things happen in the headliner vents in the back. No controls in the back seat.

    New guy here

    I've been a Dodge guy forever but bought an '02 Tahoe project a few weeks ago. Seems every time I google something related to the truck the best, most accurate and complete answers come from here so I figured I might as well sign up. This weekend's project is knock sensors and intake gasket!
