Hello everyone,

This is a semi - cross post from alt.autos.gm:

http://groups.google.com/group/alt.autos.gm/browse_frm/thread/e3243dee0824caf4/d

The problem is that with fuse #14 in, about 3.5 amps is being drawn,
causing a dead battery in the morning.

Anyway, here is the text from alt.autos.gm, if anyone can help me
locate the antenna relay, or if you have any suggestions on how to
troubleshoot the problem more effectively, I'd appreciate it.

Thanks,
Matt
------------------------

Of the following items on fuse #14:

cigarette lighter
trunk light
heater and a/c control panel
antenna relay
chime module
glove box light
voice/alarm module
trip calculator
instrument cluster (digital only)
radio

I've eliminated the following:

cig lighter (unplugged it)
trunk light (removed it)
heat/ac control panel (removed it)
glove box light (it goes out when g.b. is closed)
voice/alarm module (not included on this car)

Which leaves the following:

antenna relay
chime module
trip calculator
instrument cluster (digital only)
radio

relisted in order from most to least likely (IMO):

antenna relay (It does not raise/lower on radio power up, although I
don't hear a motor running or a relay clicking either)
radio (it shuts off with the engine, but perhaps a relationship with
the antenna?)
instrument cluster (if this is the problem, it's hopeless as I have no
idea where to start. I will say it all 'seems' dead on engine
shutdown).
chime module (I don't think this is the problem, it chimes when fuse 14

is in place, but I realize that doesent really rule it out)
trip calculator (works fine when fuse 14 is in, resets to zero on
engine shutdown if fuse 14 is out)

And so, my questions:

1) Do you agree with the troubleshooting order?
2) Can anyone tell me where the antenna relay is? I would guess it's
someplace close to the antenna.... but I don't see anything resembling
a relay on the passenger side in the engine compt. Perhaps it's behind
the glove box....?

The only other thing I can add is that it's drawing about 3.5 amps with

the fuse in.

I'd pull the radio to eliminate it from the list, but it looks like
it's going to be a real bear to get out.

Thanks,
Matt
