I have a short somewhere in my car. My battery is drained after one night of sitting. The "CSTY" fuse is blown and I have no power locks, Power antenna, Power seat, or horn. Does anyone know what could cause this? I don't know much about electronics at all so this is kinda pissing me off.

Thanks alot, Bobby.

(Could someone explpain to me also what the CTSY fuse is hooked up to?)

 

You said it yourself.. the CTSY (courtesy) fuse powers all the fun little gadgets in the car (power windows, doors, seats, interior lights, etc). Your short is somewhere in this wiring (since the fuse is blown). It's gonna be systematic... you have to go through each system that goes through that fuse, and you'll find the short.

 

Alright well yesterday when i hooked the battery i heard athe sound of a motor start in the car so i had someone put the battery cable on while i was in the car. It turned out to be thge drivers power seat motor so I figured thatw as t. I unhooked the seat and put a fuse in and everything worked again. Today when i went out, the battery was dead and all my power stuff didnt work again. I pulled the fuse and it was popped...I dont know...this sucks
