Hey. So my mothers X3 rear defroster is not working. I pulled the fuses for the rear window heat, both are working. I then pulled some other fuses thinking they could be related (mostly all the 30's) and they are all working. The switch lights up and makes that click noise, but nothing heats up back there. Any suggestions? Thanks for your help.

hiya . check the wires on the rear screen for damage . ie both to the rear screen and on the glass . you can check the volkage on the connetors should read 5 volts ish

Thanks for the reply, will do when I get home.
