Well my dumb *** left the keys in the ignition of my 02 WRX with power on in the car over sat night and all through the day sun! Well I tried to jump it and all that would happen is the horn would continuously blow Loud! So I pulled the horn relay and tried to start the car. Well I get no power to ANYTHING! My wife has a 03 WRX so I took her battery out and put it in mine. Now the horn does not blow anymore so I put the relay back in and attempted to start the car. When I put the keys in and leave the door open I get the ding that the door is open but No clock no interior light the Mileage doesn't even come up. The car will still not start. I think it has to do with the alarm. Can anybody help?

 

I looked a little closer at the Main Fuses and found out I blew the no 1 sbf fuse in the engine bay. $3.89 and I fixed it.
