91 Civic DX sedan rear window defogger

Post by TechGuy8 »

The rear window defogger is not working. I checked the following:
- the defogger fuses(under hood 20A, under instrument panel 10A) are fine.
- defogger grid is not open when I measure the resistance with the fuse removed
- The rear window defogger switch light does not turned on
- No voltage at the defogger terminals with car running and rear defogger switch pressed

I think the problem is the rear defogger switch. The light does not turn on when I press the switch.
Do I have to remove the instrument panel to access the switch?

TIA

Yes you need to remove the bezel to replace the switch, I also had to replace my defog switch.
