Good one for u guys
Good one for u guys I have this problem. When its cold i'll turn on my rear defroster and after a few momments it will automatically turn off. No problem...BUT here is where things get sketchy. I will try and turn the defroster back on to finish up defrosting the window but it won't turn on! AND....my power seats no longer work!!!! I wait for about 5min and everything is fine again???? Whats going on? THX guys! 
I think it is a fuse, do a search. I have the same problem. Defroster only works for a few minutes, and then goes off. Can't restart the defroster unless I turn the vehicle off. I've never bothered looking into it too much seeing I don't drive my car when it's nasty out, and she stays in the garage when home.

Replace your 30 amp relay (big silver box) in your interior fuse block with a standard 30 amp fuse. For some reason those relays are crap and they don't work, had the same problem, did above and works just fine now!

02blackSS is correct. The circuit breaker is a auto-reset type, it opens when it detects overcurrent and closes when it cools down inside, almost like a thermal switch.
The ones in there are crap, I don't think they are really rated at that capacity, otherwise it wouldn't have done it.
Replace it with a regular 30 amp fuse and it will stay on for 10 mins, shuts off to cool down for 2 mins or whatever the timer is set at and can be turned on for another 10 min.
Just don't set the power seat to it's stops with the rear defroster on otherwise it will blow the 30 amp fuse you put in. Hence that's why a auto-resetting type circuit breaker was put in there in the first place.

i think the defroster cuts off before it gets the rear window too hot, and if you try to turn it back on, it won't come on. i was told this anyway. never tried to mess with my power seat afterward though...besides, that's kind of an odd coincidence that you needed to adjust your seat immediately following using the defroster, don't you think?

Say you turn the defroster on, you see the light go off shortly afterwards, like under 10 min. Go and adjust your power seat, it won't work.

This was covered in several threads. Try doing a search next time.
The resolution was to replace the factory fuse with a bigger 30 amp fuse. While I dont recommend this at all, some people have been ok so far to date.

at your !passanger seat modWhile exceeding the manufactures current rating for a particular circuit is not recommended, a few guys are doing it sucessfully and they have not reported any problems to this date. Just be aware that you exceeded the amperage suggested by engineers and you could risk burning components such as your seat and defroster and any wires connecting them. You also have the risk of a small fire. Of course this is the worse case scenario, just know that your increasing your chances by doing this.
