    Not using the defogger right now obviously but want to get any nec. corrections done before warranty expires....

    Main (upper) window defroster worked ok last winter.....Lower rear window defroster last winter was useless....

    I understand coils farther apart and perhaps less voltage...but after 10 min or so being on I would only see a slight defrosting around the lower wires...perhaps a few mm above and below each coil......not enough to see out the lower back window...

    Is this the experience of others or should the lower rear window be cleared of frost.

    Sorry for this crazy question when it's 95 degrees out right now...LOL.. I took the car to Toyota and they said voltage in the coils is ok..

    Thanks for your thoughts.

    Sounds like you've nicked a trace in the lower window. Mine clears fine.
