Question about 2005 Toyota Corolla
HELP! We recently bought this car--and the rear defogger won't turn on. I checked the fuse-box and the designated fuse was fine, but noticed on the diagram that there was yet another "defogger" label right next to it that appeared to 'maybe' be a spot where some larger unit--a circuit or switch maybe--was to be located. There was nothing inserted in that spot/slot in the fuse box and I was wondering if in fact it's missing or if that slot is just there for another model's use or something. If something IS supposed to be there then that's probably the problem and I need to get one to replace it. But if the '06 Corolla doesn't require anything in that slot, then what else should I look for as potential causes?
THANK YOU in advance for any/all help!!! --David
There are 3 fuses that control the rear defogger, and 1 relay
The fuses are: 10 amp HEATER, 10 amp MIRROR-HEATER; under the dash
The 30 amp DEF fuse is in the fuse box under the hood
The relay is the DEFOGGER relay, which is on the back side of the fuse panel under the dash
Also, check for a loose wire on the defroster grid (on the back glass), this is the most common problem.

A common thing to fial on these- assumning the grid is ok, and wires are still attched to grid, is the rear def / antenna module. It is behind rt. rear quarter trim panel. The modules burn up, and also melt the connector. the module and connector would need to be replaced.

I have the same problem in my 2003 Altima. I had a friend who works on cars check it out. I watched him and when he removed the panel under the steering wheel next to the driver's door you could hear a clicking noise. He said is sounds like my defogger relay/switch is bad. I located the part and it is not that expensive. I am going to purchase the part and have it put on. I will keep you posted to let you know if it solves my problem. If it does I will give you the name of the part so you can hopefully solve your issue.

There's a junction box behind passenger rear door that has 2 wires that are joined from the front and control the rear defroster and radio antenna.
