So last week my dad's 97 Tacoma wouldn't go into gear. We found that two of the fuses were blown, the tail light fuse and I believe the headlight fuse. I'm not sure if it is the headlight fuse though because I wasn't there when he switched the fuses. Plus we also drove the car home with the headlight on after we used the override switch. My dad replaced the fuses and everything worked fine again. The other day the fuses blew again. So I figured there must be a short somewhere and I checked the wires for the hitch connection. All of those seem fine. My dad told me earlier that the fuses seem to blow when he turns the headlights on.
So what should I check for and how do I go about checking the wires for short. Also how would I fix wires that may be shorting? I am a bit of a noob at cars.
