    Several ABS codes

    Hubs with new sensors would be my starting point before other stuff. Critical safety item and, at that mileage, very probably needed soon anyway. Maybe someone replaced hubs already. But if you don't know when or with what quality... Clint would be asking... "Do you feel lucky?" I had both...

    Every other day something folks! Water pouring out of the HVAC vents over passenger seat driver side

    This thread shows where they come out and suggestions on what to do and not do... https://www.tahoeyukonforum.com/threads/unclog-sunroof-drain.101737/ The video in the thread removed the door. Probably don't need to do that, but I thought it would help you see where the drains are up top and...

    Cam Position Sensor O ring

    I had my battery on the 04 Tahoe disconnected for a few hours and when I started it up, it sputtered, stumbled and ran really rough for a few minutes. Scared me for a few minutes, I thought I really screwed something up. The ECM must have worked though its own re-learn as the computer continued...

    Is there some digital kill switch I can put on my Tahoe?

    All good advice above. I had a soft-top Jeep Rubicon, so #5 was the most important guideline for me at the time... No top and no doors in summer, you tend to not leave anything behind. I still don't keep anything that hints of being worth anything in my Tahoe. Just habit that hangs on for me.

    Cam Position Sensor O ring

    I am just gun-shy on things like those sensors... I tend to not want to mess with something critical like that unless absolutely necessary. Especially, if the sensor has the engine running nicely.

    Trouble Code 443

    P0443 is specific to the purge valve and indicates a problem with the circuit. Inspect wires and the connector to make sure they are not broken or damaged. Since you replaced the purge valve, maybe there is a chance the connector was just not plugged in solid. Pull out the harness connector...

    Cam Position Sensor O ring

    Time trying to figure out what is needed to just replace the O-ring, you might be better off just buying a new sensor. I don't even see a separate O-ring that comes up. GM Genuine is only $45 at RockAuto.com... https://www.rockauto.com/en/moreinfo.php?pk=13938061&cc=1424247&pt=7192&jsn=1671...

    Nice gauges!

    Every other day something folks! Water pouring out of the HVAC vents over passenger seat driver side

    I am pretty sure there is a drain hole in each corner of the sunroof opening. I could be wrong. If it were me, I would have wanted to see if the antenna was the problem before disabling and sealing the sunroof. Would be a shame to lose the sunroof if that wasn't the issue... I love having the...

    Every other day something folks! Water pouring out of the HVAC vents over passenger seat driver side

    I would not expect there to be any condensation from cooling in the ducts for the rear HVAC. Water between the roof and headliner would be what comes to my mind. Looking at the sunroof and the drains would be my first recommendation to check. Probably sloshing around until a low spot is found...

    200K+ club what oil you run in the heat ??

    My 04 LM7 5.3L is about 212k miles. I bought it with about 187k. Run 5W-30 year round. We get close to 100 F in the summer for short bits and I have no idea what people do in Australia or why. That said, my engine maintains normal operating temperature all year round regardless of how hot it...

    Intermittent ABS light issue

    This^^^ costs nothing. Not saying the scan tools are required to inspect hubs... Just additional tools that can usually help tell exactly what the ABS sensors are doing or confirm whether the computer is receiving the signals it should be receiving. Here is what mine looked and sounded like...

    Inspect your brake calipers if you have a g80 rear axle

    Heads-up... I put on cheapest rotors and could not get parking brake to hold anything at all. I had RMV inspection coming up. I replaced cables and hardware, before giving up and bringing to my mechanic. He spent a long time in labor, only to find out the hubs had less clearance at the inside...

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

    I am not sure if they offer any options without orange reflectors, but I got TYC brand from RockAuto. They were stock replacements. I can tell you they were same build quality, fit and finish as the originals. All the adjustment hardware (i got headlight and turn signal assemblies) and...

    Door mirrors, yes again.

    If you have a Tech 2 scan tool or someone close to you that might be willing to help... Tech 2 clone is about $300. Use it twice for anything and you will have earned your return on investment. May not be possible in the budget for you right now, but something to put on the wishlist if you...

    Intermittent ABS light issue

    I had ABS light that would remain off until I got to highway speed. Then, the light would flash and the chimes would start pining at me. When I got below 50 MPH, light went off and no more chimes. I was not having pedal pulse or ABS activation. Mine was the opposite. It was warning me that ABS...

    Help

    Loose connections on the cables or battery terminals can do that too. I stripped out the bolts on my battery clamps. I used toothpicks to give the thread some bite to get me to work the next morning. Worked, but eventually loosened up. Started and drove. Went a mile down the street and parked...

    2008 Yukon gas tank issue.

    I got a code/CEL a few months back. This is what I got when my purge valve was not working. I believe it was sticking in the open position and threw this code when it happened. I agree that issue on this thread is not a purge issue, but a vent issue. Vent tubes between the filler and the...

    Several ABS codes

    Just to rule out one more thing 100% before closing the books on this... Have you checked the hubs for excess play? Excess slop in the hubs, just before the hubs fail, often start with no other noticeable symptoms other than ABS speed sensor codes. Just for peace of mind, I would make sure the...

    Inspect your brake calipers if you have a g80 rear axle

    I won't go to a shop that is TOO clean. A mom & pop shop with oil and kitty litter on the floor is usually the kind that is busy enough all day and barely have time to sweep up between jobs. If they're that busy, then they have enough repeat customers to fill their day from open to close. A shop...

    Escalade roof rack side bars compatible with Z71 rack?

    Yes. Opportunity for confusion all over the place. My interpretation was that he was looking to go with that sleek, low-profile look the Esky racks offer while maintaining the robust functionality of the Z71 roller. A swap would be possible, but would be all or nothing and would probably...

    Door mirrors, yes again.

    Does it do this when Seat/Driver 1 is selected? If the switches are non-GM, maybe the seat/driver selector button has wires backwards. Try it and let us know what happens on #1. I raise this as a possibility, only because I have heard members seeing aftermarket mirrors that go up when they...

    New shocks

    Are these Bilsteins original to my 04 Z71 or were they an older upgrade? They look like they might be original. They have good patina... With the Z71 suspension, these ride beautifully and work great for however old they are. Bumps, railroad crossings, rough roads and highway... Handles all of...

    Did you make your own or where did you buy the Big 3 set?

    2003 Yukon XL SLT DIC and climate control backlights not working

    I'm in the same boat. Mechanical stuff trumps instrument cluster.
