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.

The rear defogger is fuse #14 (40 Amp fuse) in the underhood fuse box,no other fuses, I have the owners manual. If the fuse checks good test the heater grid of the rear defogger, it is most likely is an open circuit, it can be repaired by the dealer or u..

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.
