Does anyone know the correct voltage my multimeter should register when measuring at the drivers side and passanger side connecters of the rear window defogger?

 

What issue are you having?

There should be 2 wires to the connector. The blk wire is ground. The other wire will have battery voltage, so ~12V.

If you unplug the connector, you should get 12V across the two wires. If you have 0 volts, then you need to determine if the power or ground wire is the problem.

If you get a 12V reading on this static test, the issue could still be the wiring/relay.

 

Thanks for the response. I am getting just under 10 volts when measuring at the drivers side with the red multimeter wire and passanger side with the black. The grid does not seem to get warm enough to melt ice and snow effectively.
