Dead Battery.1993 Lumina Z-34

[mac1834]

The battery will go dead in two days if I leave the #3 fuse (ctsy) that is located inside the glove box in place,. I have checked all the lights and none are staying on. This fuse also controls the door lock switches on the door panel. If I remove the fuse and do without the lights and door locks it is OK. Has anyone had this problem?

parasitic load, for some reason something is sapping your battery, could be a bad door lock or something. but it is something on that fuse that is shorting out somewhere and draining the battery. check into the wires and find out where they go, use a multimeter and test them. if you find one with irregular volta compared to the other you have found your problem.

Thanks for the tips. I'll start checking out the circuits. The door locks work fine when the fuse is in. Also the doors locks work when the transmission is put in gear even with the fuse out.
