More New Owner Questions

[scott-c-arnold@xxxx]

As a new owner, the biggest problem I have is understanding how 
various parts of the car are supposed to work (this is a problem 
because most of the systems on my car do not operate correctly -- if 
I haven't fixed it, it doesn't work!). For instance, it was weeks 
before I understood how the dome lights were supposed to work. I have 
never seen dome lights that work in such a fashion. Anyway, I 
currently have 2 questions along these lines that maybe someone can 
answer before I start tearing up panels and tracing wires and figuring 
it out on my own.

1) Rear defrost -- My dash bulb was burnt out, no big deal. Now that 
I have replaced the buld, pressing the switch forward turns the bulb 
on but the bulb turns right back off when I release the button. This 
*may* be proper operation since the car isn't cold. However, the rear 
defrost may also work on a timer, in which case the system would not 
be operating correctly. Can someone tell me how the rear defrost is 
supposed to work?

2) I have the rear mounted power antenna. And of course, I haven't 
fixed it yet, so it doesn't work. From what I read, there should be a 
relay for the power antenna behind the seat of the car? But this is 
not really the information I am looking for. My power antenna has 2 
wires running to it (not including the actual antenna connection). 
Furthermore, the bracket it is mounted to is a good ground (whether 
or not this ground is used I don't know). The two wires running to it 
are red and green. Both of these wires have 12V power at all times. 
This can't possibly be correct. Before I start dismantling the power 
antenna, does anyone know what these wires are supposed to do?

Thanks,
