    Fog light switch problem

    David, The bulb(s) are most likely burned out: You should have illumination of FOG LIGHTS when dash lights are on and a second amber indicator when the fog lights are on. You have to take switch apart to get to the bulbs and they are soldered in. I have done it, so it can be done. Tbruz

    Fan Clutch question

    Pretty sure the Fan clutch on my 1997 2 door is the original with 123K miles. Spinning it by hand is just as easy stone cold as it is when hot so I'm pretty sure it has failed. Also I hear no roaring on cold start nor do I have any issues with overheating. It there a more accurate test...

    Steering saga part II

    1997 Tahoe 2 door 4WD. So I wasn't able to solve the Jittery steering with a new steering sensor as I had about two years ago. The truck ended up needing a new pitman arm and idler arm as well along with an alignment. Disconnecting the EVO sensor behind the PS pump appears to eliminate the...
