Hi. Other owners have reported similar symptoms with their trailblazers. The first and easiest thing to check would be the 125A mega fuse under the hood. This is located right outside the under hood fuse box and has two big power connections on each side. Make sure all the bolts in that area are tight as a loose connection could also be the cause. If the issue persists, have a certified technician, such as one from YourMechanic, inspect the electrical components more in-depth to find the source of the problem.
