i have a 2000 nissan maxima and started to have a battery drain. my remote and passenger side lock switch has not woked in a long time. so i finally changed the battery in it works now and so does door lock switch (think about same time) i have traced it to the window fuselink. so i stared to disconect all the window and door lock switches pulled all light bulbs pulled wires from sun roof. only things i couldnt remove wires from was power seat and the trunk lid and gas door latch. (still draining) is there any thing else that may run off of same fuselink? or any ideas on what i should do next? ampmeater bounces up to 0.32 back down to 0.07 thanks for any ideas

HELP !!!

 

Do you have an after market alarm in the car? Many of those alarms will start drawing too much current and whoever installed it may have tapped into the window circuit for power.

There are several things that get power from the 40 amp fusible link for the Windows. The sunroof, the seats, the windows, the door locks and the SECU module. The SECU module uses the power for the door lock controller, the NATS and the Homelink transmitter in the sun visor.

The stuff in the trunk that you couldn't disconnect doesn't get power from the window fusible link. Have to unplugged ALL of the power window switches? Unplug the SECU and see what happens.

 

no all OME. and yes i have unplug all switches but not SECU module.
what and where is the SECU module? when i click door locks i hear a clicking noise from under the dash by steering wheel?

 

The SECU is under the dash between the steering column and the center console, above your right knee when you are sitting in the car. It is a cream colored box on my car.

 

yes i see it, that is whats makeing the clicking noise even with fuselink out? will check it as soon as i get a friend over and let you know. i have broke both wrist and can't get under dash very ez.

thanks for help

 

Sorry about your wrists, that probably does make things a little more difficult.

I don't really know what is making the clicking noise. I don't think that the SECU can even do that.

It could be a relay. There are several relays under the dash, 3 on the back side of the fuse block (ignition, accessory, blower motor), another one to the right of the fuse block (window) and another 2 down by the floor behind the kick panel (fuel pump, rear defogger).

It could also possibly be the circuit breaker for the windows and seats, which is located behind (but not attached to) the fuse block.
