Thank you, what bugs my it seems to do it when I drive it I thought it was my key that has a resistor in it, and had something to do with the security system but the maxifuse I don't think has any thing to do with that so.

I looked in my 98 manual and there isn't a maxifuse for horn, turn signal, and trunk.

OK , there are two banks of maxifuse's on the firewall, this fuse is in the right hand bank which is passenger side and it the fuse all the way two the left if I recall it may be one back from that. I can take a picture of it if that would help you help me?

If I read my manual right, the right hand bank starts from the CENTER,
PWR WDO/SR Circuit Breaker 30 amp
HORNS/DR LKS/TRNK RLY, 60 amp
SPARE, 60 AMP
PCM/VATS, 20 AMP
A/C, 30 AMP
IGN SW, 60AMP
SPARE, 40 AMP
Is the fuse you're looking at a 60 amp? Which is next to a 30 amp fuse on the end? That would be the Horns, Door locks, trunk relay.
Power from there goes to 3 fuses inside the car. So you canr emove those 3 one at at time to see if that cures your drain. You could also remove all 3 and see if your problem is gone, then put them back in one at a time and drive to see if your problem returns. The fuses are IP Junction block, #1 20 amp for door locks, #2 15 amp for RAC/trunk relay, and #3 for Horn 15 amp.
The RAC module appeared here on this fuse for the first time. I assume that means Retained Accessory Power. That's supposed to keep things like radio and interior lights on for about 10 minutes without the ignition on ON or ACC.

Is the RAC module different than the BCM and can you tell about where it is
located? I am thinking thats it because my wife can drive the car three weeks
and nothing happens but the first time I do, the next day it dead so, she
lingers in it when she parking I don't and it may be related to the resister in
our Keys. also can you tell me how much the draw should be on the Battery
when the car is in sleep mode how many miliamps?
