So last night I finished Hardwiring my fan to a switch that i can manually turn on and off. When I try to use my parking lights, The fuse just blows right away, it seems like I can hear a whining sound just before it blows. Is there anywhere in particular that is likely to short out? The fuse for the fan and the parking lights are different fuses. To wire the fan i used the fan relay and just completed the ground so the fan will turn on if the switch is on and the key is in the ignition. Are the parking lights connected to a relay? And if so, is there any possibility that I unhooked something or blew any relays while I was serching for the fan relay? Please let me know what you think.
