One problem related to horn assembly has been reported for the 2003 Chevrolet Blazer. The most recently reported issues are listed below.
Takata inflators: I had left my house headed to work at approximately 6:30 am and got on i40 eastbound, it had snowed the day before and the roads had been treated and were clear for travel, I was traveling on a 3 lane highway in the left lane @ aprox 50mph and I applied my brakes to do upcoming traffic, when the abs system locked. I attempted to let off and re apply the brake but the abs system just stayed engaged and the front end started sliding hard to the left and I steered away from the pull. I subsequently hit the center concrete wall at approx. 40mph with the front passenger side of my car, which caused me to spin around and hit the passenger rear, I continued to spin until I was facing back east. My air bags did not deploy but it caused severe damage to core support and passenger side frame horn. It was a single vehicle accident and no damage was done to anything but my vehicle and myself, the abs did not release within what I approximate to be about 6 seconds and this so called safety device nearly killed me. I was wearing my seat belt.
