Alrighty guys Im on vacation 7 hours from my home.... needless to say I didnt bring alot of my tools...Ive been searching for the answer but havent been able to figure it out so Im askin you guys....

ok heres the deal, i have an rb swapped rps13. I have a huge pull from sumwhere. narrowed it down.

I have found that when ever i pull the window fuse labeled ENG CONT (FL25A) in the passenger side of the engine bay (chasis panel)the pull goes away. So sumthing attached to that fuse is shorting out.

So heres my question..... What is attached to this fuse??? What does it control??? And is it needed for safe operation???? Any help would be greatly appreciated.... thnx n advance fellas....

bades, pull it. see if the car runs. if it runs and drives its not necessary for operation lol

It is cake if you already know what circuit it is on. Look up the FSM for the S13 and go to the wiring diagram for that window switch.

Assuming the wiring is not shorting, I'm going to say the window motor has crapped out.

Oh christ, sorry dude. I misread the post and thought you said you pulled the fuse for the windows and the draw stopped LOL.

Good work finding the problem, time for a better quality battery I suspect.
