2001 Chevrolet Blazer Q&A
2001 Chevrolet Blazer Question: ABS & brake lights come on simulateously, but is intermitant problem.
Most likely a wheel speed sensor problem, scan test will confirm but scanner really needs to be connected at the time of the falt! May have to let a mechanic drive it with the scanner hooked up until this happens, that is IF no memory codes can be found. - pushrod
yes wheel speed sensor is erratic - globalhelper
