I have a 2000 blazer zr2. The other day the passenger side window stopped working. The master switch powers the drivers side window correctly but does not power the passenger window. The passenger switch does not work at all. I used a circuit tester to see if the switches were getting power, the master switch is getting up and down power at both drivers side and passenger side, but the passenger side switch is not getting any power at all. Passenger power locks work, but not the window. I also replaced the passenger switch, but still no power. What could be causing the passenger side power window to not be getting power?

 

I am assuming that all ZR2's are 2 dr.

Is there 12V on the Dk Blu wire with the passenger window switch in the up position and on the brown wire in the down position? You will have to back probe the wires behind the socket

Now pull the connector off of the switch. Is there 12V on the Dk Grn wire and ground on the Lt Blu and Tan wires?

At these ages, I've noticed that the switches themselves can have issues. It is worth checking them too.

 

This testing sequence does just that Christine. It checks the passenger switch and the ground pass through of the drivers switch as well as the wiring, power and grounds.
