I just bought a 99 Blazer LT. All the power windows work, but only from the driver's controls. I made sure that the window lock wasn't on and still none of the other doors can control their own windows, to go up or down.

Could this be as easy as just replacing the window lock switch (is that easy even?), or could this be something more serious? I inspected the fuses already, not sure what the next step in dignosing will be...

Thanks for the help,

You are correct, the only component between power and the passenger switches is the lockout switch. I have seen them installed backwards in the bezel try both positions.

 

I've tried both positions already, first thing I did actually. It sounds like the switch might just need to be replaced.

Any other ideas before I just go ahead and but a new switch?

Thanks for the help.

 

unplug the connector and put a jumper between the wires, should work then or it's not the switch.

 

There are 4 wires that connect through a harness, a Blue, Brown, Green, and Black. Do you know which wires to bridge together to test this?

Thanks

 

I pulled the switch and cleaned up the connectors and it worked!

Thanks for all the help guys...
