melted fuse box 1989 toyota camry	Sign In

I was driving on the highway, suddenly the windshield wipers went ballistic, I could not turn them off so I pulled over on the shoulder. I thought, disconnect them or at least pull them off the windshield to prevent further scratching but as
I came to a stop and the engine returned to idle speed the wipers stopped,but as soon as I accelerated to return to the highway they started again. I returned to the shoulder and shut off the engine.I then discovered I had no power.
I popped the hood and found the fuse box holding three fuses right next to the battery connected to the positive
battery cable, had not only blown the middle fuse (eighty amp), it had also melted the plastic that contained it. I have ordered a fuse box replacement, and removed the steering column covers exposing the wiper switch assuming that it must be replaced as well, although I am not to clear on how to remove/install this part,or if indeed the problem began with the wipers or if they are a symptom of a bigger problem. There is a low amp wiper fuse inside car that is still good. Is the wiper motor and connector switch a single unit located on the steering colum or is the wiper motor a
separate unit located in a different place? My vehicle has a 2.5 liter v6 engine. Would wiper parts from a 4 cylinder
be compatible? Should I replace these parts now? or first install the blown fuse and f. box?

If you melted the main 80A fues I would suspect the man batter cable has rubbed agains somthing and shorted to ground. Follow the cable and see if you can see where it's shorted.

There could also be a problem with the alternator itself shorting out internally if you don't find wiring grounding out somewhere. You might want to be sure that is good before sticking another fuse box in unless you wanna see that one go up in smoke also.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
