Chevrolet Blazer, GMC and S10 Four-Wheel Drive Repair, Complete Vacuum Hose Routing and Replacement

Hello, and welcome to my YouTube channel. Today's video is another vehicle repair episode. Two years ago, my Blazer did not want to engage into four-wheel drive. At that time, it turned out to be a faulty vacuum actuator for the front axle hubs. Now this year, I encountered the opposite problem the Blazer did not want to disengage from being in four-wheel drive. I found a broke vacuum hose underneath the vehicle and decided to update all the vacuum hoses related to the four-wheel drive operation. This video goes into detail all the vacuum hose locations and replacing the hoses. While I changed the vacuum hoses, I also decided to change the transfer case vacuum switch at the same time. I hope the video helps you out, and feel free to comment below, and check out my website that is a work in progress.
