This morning when I started my 02 Discovery the heat would not work nor would the windows the heated seats not even the seats themselves would not work. After I drove for about an hour stopped for gas everything started to work again mind you it was about 14 degress lastnight so do you think a certain portion of the electrical system was frozen? Thanks in advance.

What you describe is not cold related, Rovers take the cold real well.

Puzzled hmmm

The battery is only about 3mos old and it it a heavy duty truck battery with well over 1000cca. I had always thought Rovers adapted to cold very well also but I am still puzzled hmmm.

If the engine started, I would doubt the battery would be an issue.
A group of electrical items not working, and then after time all these items start working again implies a circuit in the power supply system has failed temporarily. Take caution. This bad connection could be a source of heat and therefore burned conectors, probably somewhere within the fuse box or some type of power distribution area.
Sorry I can't be more specific.

Have the local parts store check the charging system anyway, should be between 13.6 and 14.4 volts. Also check all your grounds.

I agree with Frogeye and Disco Mike, there's a common point somewhere in the electrical system that feeds all the items you said didn't work. Looking at the electrical diagram, nothing jumps at me right off the bat, but I too would begin by checking all the earth headers so that they are tight and clean. Not working when cold and then working when hot suggests a loose connection or a cold solder.
