  1. How-To: Lighting & Electrical
    I recently purchased a 2010 Colorado with a 3.7L. The mileage on the odometer is not correct as the mileage reported on the title when it was purchased by the previous owner 2 years ago is only 36 miles less than what the actual mileage on the odometer now. I do a lot of traveling so I want to...
  2. V8 Engine & Drivetrain
    I'm sure this problem has never come up, but I am the king of weird electrical problems that no one has ever had. So with that said, let's get to the issues and what's been done. I bought this truck brand new in 2012 and other than the exhaust, it is bone stock. I have had relay issues with...
  3. Engines/Performance/Tech Questions
    I'm new new to the forum and apologize if I am posting this in the wrong area. I just recently purchased a 2005 Chevy Colorado LT crew cab. Has 4 wheel drive and 38 k miles. Sometimes, not always, when i leave the vehicle and return the radio is on, or windshield wipers. Basically anything left...
  4. Electrical/Lighting/Security
    Quick question here... I'm trying to wire up a relay under the dash that is switched on with the high beams. The high beams (and flash to pass) are both ground switches, meaning they are sent voltage from the BCM and when the switch is closed, they complete the circuit to a common ground to...

  6. Audio/Multimedia
    I got my Colorado a couple of weeks ago. First thing I did was order a Bluetooth interface so I could stream music. I was disappointed at the limited options for integrating with the factory radio, but the reviews on Amazon for the iSimple ISGM655 were encouraging. I'm having a problem keeping...
  7. Engines/Performance/Tech Questions
    Hi, I've been lurking around hear for a few weeks. I have a dead Colorado at the moment, typical anti theft bull. There's a lot of good information on the whole VAT and BCM troubles that plague GMs here. But the one vital piece of information I need, I cannot seem to find anywhere. So, does...
  8. Electrical/Lighting/Security
    Since I purchased the 2005 truck back in November, it seems like its slowly falling apart, but I was wondering if any one has ideas as per my Wipers, they did work and now they don't. I have checked the fuses, wiring etc... Even brought it into a shop intown that assured me it was the BCM. I...
  9. Engines/Performance/Tech Questions
    So I thought I had finally fixed my issues with the warning lights coming on but come to find out I had been diagnosing them incorrectly. The nice thing is the problem is very repeatable. While driving, or sitting in the driveway with the transmission in neutral, If I punch the gas and run the...
