power window trouble
 

I got a 99 blazer and i just found out today that only the driver side door can control the windows. the passenger side switch wont work nor will the back windows the only way to get them down is using the driverside controls. My first thought was the lock was on but i had off and it still didnt work. does anyone know what this could be?

see if you have power going to the other switches

the master switch might be bad (driverside)

does all the other switchs run from that master switch

It is very likely your lockout switch bad.. Pull out the switch panel and look for the Dark Blue wire underneath that switch. If the switch is enabling the other switch panels it should read 12 v to the car chassis.
If it doesnt show 12v in either position jumper it to Dark Green wire which should be 12v with key on.

There is another dark blue wire but that should be under the driver window switch. It goes to that window motor

Or the harness {follow from behind kick panel} connector in the dash behind or near the IP fuse block. Also Dk Blue- Dark blue
