    Aftermarket unit issue 6 years later

    Well that's the thing, manually turning on the cam works, but not when backing up so cannot be bad AV connection. I am having hard time believing that is it the HU, even though all points to it. Does everything else function as normal in you HU? I am leaning towards reverse wire issue somewhere...

    Aftermarket unit issue 6 years later

    I will check. Am I looking for absense of resistance? Also, what would cause camera to work manually? If the center pit is at fault, why would it work manually?

    Aftermarket unit issue 6 years later

    Doubt that it is the camera. As mentioned in step 6 above, I connected AV source (front camera) and still no result.

    Aftermarket unit issue 6 years later

    Alright gents, you're my last hope. In 2014 installed Pioneer AVH-X8500BHS into my 2010 Tahoe with Bose analog amp with RPO UQA using Metra's harness, ADBOX1 module, and ASWC to retain factory controls. All was working fine up until 2 months ago when factory backup camera stopped engaging in...

    Bleeding brakes, sucking air from Master cylinder?

    I just did this on my 2010 Tahoe. Rear passenger side, rear driver side, passenger side front, driver side front. Used pressure bleeder. Once finished, used Tech2 to bleed air out, you might want to try the same. Each bleed takes about one full master cylinder to ensure to fill up after each...

    B2470 Error code from OnStar - Red light on rear view mirror

    I spoke with them and was told to take to a dealer. Go figure. I have to take my radio out to install front camera and will then test the VCIM and coax for continuity and resistance.

    B1000 and B2470 DTCs

    Did some extensive searching and couldn't find anything for these specific codes. B1000 3C ECU performance and B2470 Symptom 4, Cellular Antenna Open Circuit. Are they related? Some suggested cleaning the ECU harness and some to replace it. As for B2470, the shark fin antenna serms intact. I...

    Airbag light DIY or send it to the dealer?

    Yeah, the insurance estimated 16k in damage, we fixed it for around 3k. I understand the resale on rebuilt is shit, but the intent was, and currently is, to keep it until it is dead. The temptation for 2021 GM is centrantly overwhelming at times as I am blessed with steady income, but the 'want'...

    Can someone help with trailer braking?

    I realized that I enjoy hotels more not because of the cost or difficulty traveling with the trailer as after few hundred miles I did and few backups/backins towing with F250 was very easy. We have a 9 yo and a 1 yo and they go NUTS! 33ft seems big until you stay in it for a month or two with...

    The repairs were done by me and a friend in his shop 6 so so years ago we we did not do anything but replace rear fender, bumper, adjust a frame slightly, paint and later I replaced the entire differential as the axle was bent. I eared the code yesterday and it did not come back right away. Will...

    Passenger side heated seat, top and bottom, stopped working roughly 3 years ago. We were (and currently are) in hot climate so I never made it a priority. We will be likely moving to a cold climate and would like to get this fixed. When turning on, the passenger heated seat light stays on for...

    Can someone help with trailer braking?

    Well, general consensus here was for me to get a truck to keep it safe so I towed it with F250. Despite shitty gas milage (around 10) it pulled ~7000lbs just fine. I really want to try the Tahoe for this job as I installed brake controller, upgraded my rear shocks to air shocks, got extended...

    Can someone help with trailer braking?

    Coming back here after months to thank you dudes. We finished our 2000+ miles trip roughly 2 months ago and all went well. Wife loved it. I came to find out that I rather stay in hotels. However, camp site at Fort Pickens, FL was amazing!

    Broken Folding Mirror (non a typical issue).

    Gave up on this shit after 3 days and bought a complete set from a local just yard for $50. All is working fine. However, I am almost certain that the shaved collet game me issues. I did not want to take apart my driver mirror to compare or the mirror I got from a junk yard.

    Airbag light DIY or send it to the dealer?

    Don't mean to hijack this thread, but have somewhat similar issue.

There are bulletins...
