    2007 Tahoe

    In the last few days I've noticed my battery gauge fluctuating between 13 and 15. I have a chip in to turn off the fuel management system and that seems to still be working. No symptoms of bad alternator. From what I'm seeing this fluctuation may be normal but I didn't notice it until recently...

    2007 Tahoe Z71 - Auto Climate Control - No Front Blower

    My 2007 Tahoe Z71 front blower is not working, it went out a few weeks ago I knocked on the housing a bit and it started back up. It is now completely out, can someone tell me how to determine if it is the resistor or the blower motor? I would like to replace myself as it seems to be the same...

    I've contacted the dealership twice and received the same response from them so, I've reported it to the BBB and wrote up a review for the dealership. When history was checked on the code it did only show it coming up after I purchased the vehicle and from what I told they can't clear it from...

    My cousin is a mechanic, I'm going to have him check the code this time and pull history. If I'm not mistaken it will show dates and codes in the history, maybe I can use this to my defense.

    I had a 2000 S-10 Blazer and a 2005 Trailblazer LT. The Blazer had multiple issues but the Trailblazer was the best vehicle I've owned. Almost hit 300,000 miles with no major repairs and then the transmission went :(

    I think I might give that at try, thank you for the advise. Used dealerships I've dealt with in the past have always been more than happy to help if a issue came up on my vehicles even if purchased as is. So, I was a bit shocked at their response when this happened less than 24hrs after purchasing.

    I immediately notified the dealership and asked if I could come into their service center to figure out what was going on. They told me that wasn't an option and that I'd be better off using my own mechanic because theirs are GM certified and $130 an hr. I'm obviously not pleased with this...

    Recently purchased a 2007 Tahoe Z71, less than 2 hours after leaving the dealership the check engine light came on. Code is P0420, should I jump right into replacing the catalytic converter or is there something else I should be looking at first? I was told it could be from condensation, a...
