    Stalling At Idle

    I have an 08 Tahoe LT 4x4 with the 5.3 in it and around 135k on it. I only drive it primarily on the weekends because I have a work vehicle. A few weeks ago while at an extended idle and in park the engine died. I turned the key off and on and it started right back up immediately with no CEL...

    Bluetooth mic placement

    So I added a factory VCIM, plug and play with built in Bluetooth antenna, recently from a newer vehicle to give my 08 Tahoe factory hands free phone. It works flawlessly. I want to stream my music though and due to the unavailability of the add-on modules that just do music streaming, I ended...

    Bluetooth Adapter

    I am looking to buy a Bluetooth adapter for my 2008 Tahoe. I’d like to get one of the units that plugs into the XM module behind the glove box. I already have Bluetooth for the phone so I am looking for one of the adapters that does only music steaming. Crux makes a BTS-GM1X and ISS Automotive...

    Air Cleaner???

    So I was just looking online at air cleaners for my 2008 Tahoe LT 4x4 5.3 and I keep seeing multiple options for “with high capacity air cleaner” and “without high capacity air cleaner”. How do you tell which air intake box you have? I could look at the part number of the existing air cleaner...

    Aux Input

    Hi, So I installed a new VCIM and I get Bluetooth over the phone now, and I bought a USB C to 3.5mm aux cable to use my iPhone 16 Pro to listen to music through my 08 Tahoe non-Nav with Bose. It works but the audio is significantly quieter than through the stereo than the volume of the radio...

    2008 Tahoe LT VCIM Swap

    I have a 2008 Tahoe LT with XM and Bose but no nav and I am swapping in a 2010 Continental VCIM to get factory Bluetooth functionality for the phone. I have a question on the mechanicals of it though. I took off the trim piece around the radio/hvac and took out the bottom module for the power...

    Power Window Switch Question

    Hi, I have an 08 Tahoe LT. The passengers side rear power window switch recently quit. Window operation still works from the master switch on the drivers door. As far as switch replacement goes, does a brand new switch need to be programmed? If I get a used switch does it not need to, if a new...

    Backup light LEDs

    Hi guys I’m looking to replace my backup bulbs in my 07 Tahoe (bulb 7441 I think) with LED plug and play bulbs. I have read that the DieselLED style with the harness protruding from the back is the brightest option but I do not like how they don’t lock into the housing. I’m looking for a more...

    Alignment - Front or 4 Wheel?

    I have a new to me 08 Tahoe LT 4wd. I have an alignment question. Is the rear of these trucks adjustable? I need an alignment but I’m not sure if it’s actually possible to adjust anything in the rear or if it’s the front only. All replies appreciated. Take care

    Mixing Tires

    I have an 08 Tahoe LT with about 125k in the clock. It’s a regular 4WD model, not a full time 4WD or full time AWD, but a regular selectable 4WD. I bought it recently and it needs front tires. The backs are still good for a while. It has Goodyear Wrangler SRA on it now. I found a pair of used...

    Front floor mats

    Hi I have an 08 Tahoe LT. When I recently bought it, it came with front floor mats. The seller says they are weather tech, but I can’t find an insignia on them. Whatever they are, the drives side may doesn’t stay in place and almost every time I get in, the lip which is at the kick plate area...

    Stuck in 4WD

    So bought an 08 Tahoe LT 4WD 5.3 in June. I have a work tuck so I use the Tahoe only occasionally. When I bought it, it had a “service 4wd system” message and an associated C0321 code. Today when I was driving it I felt something weird when going around a corner along with a whine. I then...

    Stabilus brand lift gate supports

    So my lift gate stopped functioning properly with it starting to open about a foot and then reversing and closing. As noted here many times, it seems I need lift gate supports. I just ordered a pair online. They are the stabilus brand. One side has part number 3B807349 and the other has part...

    Gas Tank Door

    So I have a new to me 08 Tahoe 5.3 and I noticed the gas tank door is rubbing the body on the hinge side when opening and closing. It’s hard to open and close as well. Is there a track behind the body that some rollers ride on that came off or something or is it just a regular hinge? It doesn’t...

    2008 Tahoe Reverse Sensing System Questions

    So I recently bought an 08 Tahoe LT and it has the factory reverse sensing system option. It has 3 lights on the passenger side inside D pillar which I think are green, yellow and red. These seem to work correctly but I am wondering about the audio. I get a beeps when I go into reverse and I...

    Battery vent question

    So I bought the Exide Sprinter Max battery at Home Depot today. I noticed that it has a vent elbow coming out the side of the battery near the negative post. I can rotate it 360 degrees. My Tahoe is new to me but I’m not the original owner. Is there supposed to be some sort of factory vent tube...

    Exide Sprinter Max Battery???

    Anyone here running one in their truck? Any good? The price is right at Hone Depot. It’s a regular flooded battery not AGM or spiral cell but the cost is a fraction of those. Anyone have experience with these? Thanks

    VCIM for Bluetooth

    I’ve been searching possibilities to add Bluetooth to my 08 Tahoe LT with Bose and no Nav. I came across a few threads about using a VCIM from a newer trick to get Bluetooth for the phone. Does this still work? I read that there are a few different makers of these VCIM modules and some said the...

    Updated Key Fob?

    So there’s a company called Boost Auto Parts, with whom I have never done business, that sells the newer rectangular style key fobs for use on our platform trucks. Does anyone know if they do any modifications to get these to work or if they’re just plain oem remotes? If they’re not modified...
