OK, This will require you to extract the codes from the diagnostic port, located under the driver side dash. To achieve this, you will need to purchase a diagnostic computer(hand held). These computers are configured to pull all DTC codes from your vehicles CPU. Once you have obtain the CPU, simply, plug the diagnostic cpu into the diagnostic port, under the dash. Once plugged into the vehicle cpu, follow the instructions on the screen to extract the codes.

Now, This is the only way to extract the codes. If you are not interested in purchasing a Diagnostic CPU, I would recommend to take this vehicle to the local Autozone parts store, asap. The parts store will scan your vehicles cpu for codes, free of charge. They will give you a print out of the issues, and a recommended repair option, as well.

SOURCE: 2005 CHEVY +TRAIL BLAZER ABS AND BRAKE LIGHTS ON

When the ABS light is on when driving there is a problem in the anti lock brake system and you will need to have it tested to find out what the problem is. As long as the light is on the ABS has been shut off by the computer until it is repaired. There could be problems with one of the wheel speed sensors, wiring or the ABS pump. On some vehicles the red brake light will come on too.

SOURCE: where are the sparkplugs located on a 4.2 inline 6

Under the top of the engine there is a cover. Remove this plastic cover and under you will find an individual coil on each cylinder held in place by a bolt. Unplug the coil, remove the bolt that holds the coil in place and twist apull up gently to remove the coil boot. Under the coil is the plug. Use platinum plugs that are rated for about 80k miles so you don't have to do this procedure but once every few years. Hope this helps, good luck

2004 Chevy trail blazer hesitating while driving, and check engine light blinking.


Since the Check Engine Light (CEL) is blinking, it is indicating a serious failure condition. You need to have the car scanned for fault codes to determine the failure. Do not drive much longer with this condition, you will damage the catalytic converter.

2005 CHEVY +TRAIL BLAZER ABS AND BRAKE LIGHTS ON


if chains caused problem and you have driven with them off light would have gone out once it saw everything working properly. look at sensors might have pulled a wire loose with chains. the abs system runs a self test everytime you start vehicle if it sees a history code from last time it will leave light on and look to see if that problem still exists and 99% of the time it will cut light off . but need to have scanned and checked out
