Installed new oxygen sensors but light is still on


You need to clear the check engine light with a scanner. If you clear it and light comes back on check for a new code number. If you bought your parts locally the parts store should scan/clear your codes for free.

01 Chevy Silverado 4 X 4 not working. 4WD light


Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.
