Thanks for the feedback

I hope you keep your TrailBlazer for a long time. I have a Buick Rainier V8 which is effectively the same vehicle. Very much appreciate your videos.

I’ve done a ton of work to it. Will keep it until it dies

You can use a spray cleaner made for electronics. Here’s a link to a video I did showing how: czcams.com/video/k7lFCNORB7U/video.htmlsi=1LD6imt5a-bpAM-C
