1992 camry 2.2 automatic with 300K. Keeps blowing square 30 amp fuse in left side of dash behind change drawer. did it a few times and I replaced the fuse. everything fine for awhile, but now it blows the fuse as soon as you turn the key on. I installed a new ignition switch, had battery checked, new cable ends, checked alternator, but have found nothing. It acts like a direct short. anyone heard of this?

 

Is this the 30 amp Power fuse?

 

yeah, I think so. It's my father-in-law's car.

 

Power fuse go to power locks, windows, moon roof, power seat. The wiring between the drivers door and car chassis can fray, break, etc due to continuous door usage, check this wiring.
