I need to replace the antenna base and attached cable.

Three bolts hold the base to the bodywork, but I need to know what interior parts (trim?) need to be removed to get at the inner cable connections.

Remove the 3 bolts.

Remove the cable grommet from the body.

Disconnect the antenna cable from the extension cable.

Tie a long wire to the antenna cable.

From outside of the vehicle, pull the antenna base and cable assembly until the wire can be easily accessible. Ensure part of the wire is still in the vehicle

Remove the wire from the antenna cable.

 

Installation Procedure

 

From outside the vehicle, tie the wire to the new antenna cable and base assembly.

From inside the vehicle, pull on the long wire until the cable can be connected and grommet seated.

Install the cable grommet to the body.

 

 

 

Remove the wire and connect the antenna cable to the cable extension.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

 

Install the 3 bolts.

 

Tighten

Tighten the bolts to 5 N·m (44 lb in).

 

Install the passenger side battery, if equipped. Refer to Battery Replacement - Auxiliary in Engine Electrical.

I replaced my antenna mount on my 01 silverado but never could get the grommet to fit into place. You cant get your hand on it due to the tight location. I guess I need to pull on the cable from the inside to snap the grommet in place ?

I assume the I/P trim pad is the black plastic trim panel around the face of the gages and radio. The word "pad" is throwing me.

Is that right?

I had to remove my dash board top in order to get to my antenna cable. The cable from the mount only sticks through the dash about 20 inches then connects to another cable that connects to the radio. It wasn't very hard to remove the dash. Had to remove the glovebox door to get some screws out, then removed the a/c grilles, stuck a screwdriver in the grilles to pop out the passenger dash grab bar...etc....my chilton manual helped out a lot.

No, the IP trim pad is the piece that is the whole top of the dash. The part with the defrost grilles in it. Yeah, they should be calling it a trim PANEL instead of a pad. There's certainly no padding.

 

Removing that trim panel is a job in itself!

I dont know if anyone has successfully done this themselves on a Tahoe, but let me tell you I tried and it was MISERABLE!!! As I was pulling out the old cable, the wire I had attached to it slipped off, leaving me to fish the new antenna cable in with nothing to guide me.

 

For the life of me, I could not find the darn hole on the inside of the truck. I tried fishing in a longer piece of wire, a coat hanger, a fish-wire, you name it, I could not find it. I had the entire dash apart, along with the glove box, kick-panel, etc. and I still could not get to where this wire came in. There was so much stuff (seemingly HVAC related - maybe for the rear-seat air conditioning? 2001 Tahoe LT) in the way that I eventually put the thing back together after about 10 hours of trying to find this wire, and took it to the dealer to finish the job.

 

The dealer charged me $167.00 labor only to do it for me & that was money WELL spent. I would have gladly paid $400 for them to finish this because it seemed like an impossible job.

 

 

Total cost:

 

$167.00

10 hours of my time

Extreme frustration

10 bloody knuckles and scraped up arms from reaching into too-small places

 

 

My Reccomendation: This is one job that is not worth doing yourself. If you manage to not be an idiot like me and lose the leader wire to guide you back in, it may not be that bad. If you do lose the guide-wire though.... give up and dont waste your time!!

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."

      Looking for advice from this group. Took my flawless 2020 6.2 TB to an unnamed shop for routine rear brakes and oil change. Tech forgot to put oil back in after the full service and needles to say, destroyed my engine.  It’s all on their shop video so they are responsible.   I had my Chevy dealer do the analysis and they confirmed its compromised and said engine replacement. The manager said they only get GM reman engines from GM with full 3 yr warranty and the one they would put in is not same as what’s they are swapping out on 21-25 for recall.    I am looking for advice why that would be a different engine because obviously I had the good 6.2 year and replacing it has my concerns with that recall for 21-15   Also what’s the pros and cons of accepting the engine swap vs telling the shop that bricked the truck to pay up so I buy a new truck. I’m concerned about stigma resale eventually if I just decide to get rid of it after the swap or other issues showing up after the swap out.

      AFM Disabler Question

      By GN2018 · Posted

      Just looked up my records.  I've never gone over 5000 miles between oil changes.  At 46K miles, I have 10 oil changes.  I hope that will help.  I also installed the disabler last year.  I've still had a few times when it didn't seem to engage (which I can tell because the start stop feature kicks in), but for the most part, I think it's working.  For some reason, GM did not include the number of cylinders running in the information screen like I had on other models.  In my Cadillac, it shows me when it's running on 4 cylinders on the fuel milage screen.  I can't find that on my '21 Denali.
