    Spark plug heat ranges

    Has anyone done research on spark plugs for the 5.3 engine in the respects of choosing a plug one heat range hotter doesn’t matter who’s plug Currently using RT53x and ngk doesn’t offer a range hotter and auto lite doesn’t either. Exotic metals are not important copper will be fine

    control head and blower resistor front

    Back in the day actual resistors where used in blower circuits just like a real resistor was used in spark ignition points systems starts on 12 runs on 6 Vdc. Chrysler on firer wall GM used a long resistive wire special for circuit. Most other resistors were wire wound with crimped ends...

    control head and blower resistor front

    Connectors are fine. Previous owners must have changed that as it was in nice shapes. No I didnot check for signal from head at time of not operating. Was my next step but just wanted to know wheather resistor assy can destroy head electronics.

    Blower motor goes on and off

    Yea biggest cause of seal going bad and leaking out Freon is when ac compressor doesn’t work in defrost mode. Or system loses Freon pressure. Ac provides warm. DRY air to suck off moisture from inside windshield during winter months. Or high humidity cabin air. One thing to note about ac...

    Transfer box and transmission exchange

    I 200 % that OEM has one of the highest reman system. Just finding alt conpendent alternitves is hard. And there’s warranty exclusions with even OEM. If I had the room I would do it myself and know what I own. Finding someone that doesn’t takes short cuts reusing springs and bearings to make...

    Possible transfer case noise

    For the most part it was decent oil and everything has play or clearence but what kind of numbers is excessive. .010 .200 numbers would help.

    Transfer box and transmission exchange

    I seen a place somewhere Detroit gear or something like that selling exchanged trans and transfer box’s. Is this a good place to do business or is there some better suggestions out there 251,000 miles 2006 Yukon xl may as well start planning get rid out them now. 5.3 flex and I tow

    Possible transfer case noise

    Sorry was incorrect in my discription of. I meant disable button for stability control. And no I don’t use auto button for wheel control always left in 2 wheel drive. I don’t use auto button.

    Possible transfer case noise

    Does it use abs senors then for wheel spin or is there another group of sensors for traction control??

    Possible transfer case noise

    I’ve been disabling system at turn on to see if it doesn’t happen. So far no direct corollation information yet to make that determination

    Possible transfer case noise

    No ABS codes however system went nuts when I was doing donuts with it last winter. But it reset itself after shut off.

    Possible transfer case noise

    Some of that not all of it. Traction control message comes on power gets cut it well only coast and only happens on start up. Doesn’t feel like any braking is taken effect. No I am learning this system. Only been through one little winter with it. Just know the noises of changing to diff modes...

    Other then that vehicle drives normally with no sounds of anything is wrong

    Possible transfer case noise

    To my ears and feel it seems like system is in the middle of going between changes from 2 wheel and 4 wheel or thinks it’s on ice.

    Possible transfer case noise

    Traction message only appears for a few seconds then goes away. I am not formilure with this computer system. Just old world 4 wheel drive. I tried pushing button on dash to disingage system to see if that helps but have not concurred results test Happens cold or hot doesn’t mstter

    Possible transfer case noise

    Yes something is going on there because along with this comes traction message and gas pedal not responding to foot control pressure. I think that seems to me pedal control is removed by system when it sences traction problems but this all happens only on take off or starting out from a stop.

    Possible transfer case noise

    I drained the transfer case oil and refilled it. Nothing seemed out of place.
