    2006 Z71-For sale 70k miles

    I purchased the one owner 04 YukonXL w/ 120k miles that I'm finally using again just 6 years ago for a little over $4k from the agent of an estate attorney in the mountains above Malibu California. The ad had been up for a total of 5 minutes and I was first to call and first there 20 minutes...

    Less than top notch tires for a good deal in 265/65R18

    Anyone use less than top notch tires? I've got Michelins on three vehicles but keep looking around for a fresh set of 265/65R18s for driving between coastal Ct and coastal South Carolina. The Sumitomo Encounter HT 1st version can be found for sub $550 a set. As far as I know Sumitomo America...

    2006 Z71-For sale 70k miles

    The best way I've found through the years to buy a one owner vehicle from a family member or whatever is to walk up with the total cash of my offer in my front pocket. Haggle a bit after the test drive. Give them final offer AND pull out the roll and flash the crisp hundred dollar bills. And if...

    04 GMC YXL Speedo Cluster repaired and LEDs added

    Just got the speedo back from David Ryberg's company. They did a great job for the money. Super fast turnaround. I sent it priority and they got it on a Friday morning and had it in the post that same afternoon. Arrived back here on the East Coast today Monday afternoon. Excellent free return...

    GMT800 DRL Ambient Sensor Questions - Lil’ Help Pls

    Thanks. Will check the connection again. Fuses all good. Maybe I'm thinking of a diode for something else. Relay seems good. Just replaced the ambient light sensor (original turned to dust). It is in the slot correctly. Will clean pigtail contact and check again. I did pull the dash cover out of...

    GMT800 DRL Ambient Sensor Questions - Lil’ Help Pls

    I will be checking the sensor's connector in the morning. I replaced the sensor and DRLs aren't switching on. The head lamps are on instead. Swapped relays and no change. If it isn't the relay or the sensor or the new sockets and new 4114LL bulbs it has to be the big diode under the dash?

    GMT800 DRL Ambient Sensor Questions - Lil’ Help Pls

    Did replacing the sensor fix the issue? I've got head lamps on, no DRLs. New sensor, new sockets, new 4114LL bulbs, new 3157 ambers and corner bulbs. Tried swapping relays, nothing. All other bulbs are as should be, except indicators now alternate blink with corner bulbs (I don't recall that in...

    Strange lighting anomalies

    The YukonXL has been out to pasture last couple years after using it for a cross country trip. I've been going through everything for a couple weeks now to make it road worthy again.The DRLs stopped working some years ago. The right socket burned out years ago and was replaced once. I replaced...

    Best place for instrument Cluster repair?

    What was the end result? All good? I've had a small draw from the cluster as the digital gear shift slowly faded. About to get it addressed after years of keeping the truck unhooked when not in use and maintaining health of battery w/ 1.25 amp trickle charging when in use.

    Battery drain

    Local shops have lost the plot. Everyone can get on the net to look up the best place to send a cluster for rebuild. I just replaced my original radiator. Was going to source the original version from the early 2000s but went with the most recent iteration from GM. Purchased through Walmart for...

    Oil Pressure Sensor/Screen Replacement

    Cleaning out the connector on the oil pressure switch and reusing is good move. Also check the ground back there. It there's oil all over it you'll want to get that clean and squared away as well. At least that's my experience. The switch and the connector should not be failing.. it's the oil...

    Battery drain

    Original alternator? Or rebuilt replacement? Either way sounds like the culprit. Sounds good. Getting the cluster rebuilt can't hurt either, new stepper motors and everything. Years ago I considered sending mine in on trade for one with a trans temp needle. I think the Escalades had them, not...

    Battery drain

    This might sound like a stupid question but have you checked all your grounds? Whenever I've had issues I always check all my grounds and clean them completely, usually it works. Also, unhook your battery for a while. And check for corrosion. And upgrade the main ground straps. Upgrading the...

    2002 Tahoe z71 Fog lights & Rear wiper not working

    Ground strap that I always thought should get replaced right away is the one from the back of the block to the firewall. The rest of them could also stand an upgrade. Or at least maintenance. In the winter where I am these days I keep the YXL empty, the glove box open, zero crumbs anywhere...

    B2610 Code - SOLVED

    Is this the same issue caused by going to led bulbs in the map lamps? Those two lamps have two settings, one for stand alone and the other with dome light on. Was thinking of "upgrading" to some Hella yellow in place of GM # 13590791. What fog lamb bulbs did you go with? Also, are your fog lamp...

    New-Nivomats... ( Old subject/new problem ) Do they exist??

    Just a heads up; The GM 15182555 rear spring found on GMT800 1500 series Tahoe/Yukon RWD w/ "premium ride" (w/out off-road chassis) & also found on "smooth ride chassis" like the Escalade and YXL SLTs was discontinued in 2013. I should remember this because I went through all this once before...

    New-Nivomats... ( Old subject/new problem ) Do they exist??

    I replaced the original Nivomats with the GM ones (obviously later production) some years ago. Recently noticed a slight sag to one side. Either the Nivomats are prematurely failing or one of the springs is not happy. Currently looking for an old NOS OEM rear spring from the early 2000s. It...
