Review on 🔧 Dorman 901-072 4WD Switch: Perfect Replacement for Cadillac/Chevrolet/GMC Models by Christian Bar

My 2003 Suburban would not shift from 2WD to 4WD (and vice versa), only the power light (red) would come on. After seeing code C0374 I found that the most common problem is this 4WD switch. The dealer wanted to sell me his OEM version for 2.5 times the price of this Dorman switch! This does not make removal and installation any easier. Youtube even has a video on how to replace this switch. Just open the dashboard and pull out this switch. A simple solution to a potentially expensive diagnosis and repair. The error code is gone and everything works again! I'm ready for ski season!
