it's been in the upper 30s the last few mornings with lotsa dew and whatnot - chilly indeed, but no ice. i fire the rear defroster up and after a 10 minute drive, the rear window is still covered with dew...and only a hint of clearing.

my side-mirror defoggers are similarly anemic. they work, but slowly.

any suggestions to remedy or debug this?

What year is your Catera?

It usually takes atleast 5 minutes- maybe more (ive never really timed it) of driving time for it to clear up the rear window on ours. Mirrors are about the same.

it's an '01...

...i'll eyeball the fusepanel. otherwise, i'll assume it's normal.
