    Can someone Ohm a good rear defroster?

    I've replaced my rear glass a few months ago because the defroster tabs on the original glass were no longer attached to the glass.

    The replacement glass defroster doesn't work either.. I know for sure it's not the fuse or the defroster switch or the wiring. I get 12 volts at the wiring to the defroster. The problem I think is the unusually high value I am measuring between the two tabs on the glass.

    Can someone with a working defroster measure and post what the value is?

    I hope I don't have this problem now that I removed that shit of a tint it had.


    Simplicity is your best option!

      A good window will measure less than 2 ohms. A flawed early window that oxidizes will have a resistance above 20 ohms.

      I have a more precise resistance measurement number at home, but it doesn't really matter. Most low-end meters aren't going to be very precise measuring a resistance this low, and the bad window grids will be much higher.

        I just went out and tested mine for you, jumps between 2.1 and 2.2 ohms.

          Thank you! Mine is close to 2000 ohms! Damnit.
