My daughters 97 civic 4 door had a battery break or blow; not sure. She had it replaced, and the next day it was dead. I found acid all under the new battery so I cleaned with baking soda. Found 11 amp draw from rear defrost circuit. I disconnected one plug on rear window, and now only 1/10th of an amp draw. I pulled all fuses one at a time, and the draw remained, so I assume this is normal. Any possible ideas?, I know there is a relay; but don't know exactly where, info says under dash / fuse panel. Also talks about a time out circuit device, but not sure if a seperate module or what. By the way, the power switch to the defrost on the dash still lights up when pressed even with wire disconnected at rear window.

I have previous post about possible blown battery, cleaned a lot of acid with backing soda from under battery. My daughters door locks don't work; since the battery failure according to her. Fuse #51 in the engine compartment is blown, and as soon as I replace it, it blows again. I know it is obviously grounded, any known areas or ideas? I did not see any acid around the fuses, only under battery.

Does the 11A draw come through hood fuse 50? If so, the problem may be the hood fuse box.

I merged your two threads as the problems may be related.

Unplug the power lock control unit inside the driver's door to see whether this prevents fuse 51 from blowing.

unplugged power lock module, the fuse does not blow, I tested all individual circuits per a previous post, all test good, no wires are grounded at plug except the black ground wire as normal. I removed the module, and tested across pin 12 and 4 with ohm meter, it is connected with no resistance; so this means the module is going straight to ground. So I need to replace module; am I correct?

Have any local junk yards?

Not for an hour drive, I'm going to drive to Honda and give them the module; unless you have another idea. I have a 6 hour drive home, and don't really have time to drive to junk yard in the hopes they will have the 97 car. Any other suggestions. If not, then I will put back together, and she will be without door locks until I find time to go to junk yard back at home. By the way your help is very much appreciated.

The control unit from 96-98 Civic LX, HX, EX would work.

You can also buy the part on the Majestic Honda website.
