Defrosters stopped working

[johnait]

Electrical problem: Rear wiper, R defroster, and side mirror defrosters stopped working.

What I did to cause it (I think): I had an power converter plugged into my front cigarette lighter plug and overloaded it by charging my laptop.

Both items stopped working at the same time, so I have to believe the two problems must have one solution. I have tried the fuses, 2 in cab, and 2 under hood that are labeled as R wiper or defroster.

What can I try next? I am stumped.
