    Abs and brake light issue

    Sounds like the abs module needs to be resoldered or replaced. Mine intermittently had brake+ abs lights and resoldering the connections fixed it. These modules are pretty expensive. And it’s free to try (if you have a soldering iron). There’s probably people on the internet that will fix it...

    What did you do to your NBS GMT800 Tahoe/Yukon Today?

    What year is your Tahoe? I think mine must not have the pcv valve? I guess I’ll have to take off the valve cover to clean the orifice someday. Which spark plug model #?

    Smog check fail and ac quit !

    Probably not that bad if you can still fill the tank with gas normally though. Make sure the gas cap seal is in good shape too

    Smog check fail and ac quit !

    If yours is as bad as mine was, you’ll find charcoal all the way to the intake. Check that first, it’s easy and free to remove the house from the intake area and check.

    Smog check fail and ac quit !

    No. Even if you replace all the “parts” it still may do it. Mine had the line plugged with charcoal pellets cause the canister broke down. Had to remove the tank and blow all the lines out, replace the vent valve and canister. Some have had luck with a hand vac pump or blowing air into the...

    Seafoam before or after tune up

    Before. But begs the question- sea foam in the tank, or thru the tube into the engine, or directly to engine oil?

    2005 Tahoe LT front window switch upgrade?

    Viper/DEI alarms used to have window modules that would do this. You don’t have to have the alarm if you wire it correctly. All windows in my civic were auto up/down after adding the module. It would stop (maybe reversed? Can’t remember) when it sensed tension rolling up.

    Not a great fit over the hump, but for $13 if anybody needs grey rear floor mats, price is pretty good. It’s better than the smallish Rugged Ridge universal ones I had back there. Rugged Ridge 84951.10, All Terrain Floor Liner, Rear, Gray, 1999-2006 Chevrolet / GMC Silverado / Sierra 1500...

    Engine is running cold

    Doesn’t the conversion require reprogramming to turn the pin on for e-fans? Did he do that or just “hard wire” them?
