Fuses??

This morning I was on my way to school and I noticed my Tach, Clock, Turn Signals, Temp Gauge, and Fuel Gauge were all dead, however my speedometer worked.
Later me and my friend found it was a fuse that was blown, so I replaced it with one that was provided in the Fuse Box.
Well after about 15 minutes of driving, all those same things go out, which really pissed me off.
I had my defroster, heater, and headlights on, so I wondered if having all those on surged the fuse??
What would cause two fuses to blow within that amount of time?

According to my manual, that fuse (#3, 10 amp) powers the following things.
warning lights
clock
chime
gauges (except speedo, it's mechanical)
back up lights
turn signals

I would first check the bulbs and sockets for the turn signals and back up lights. Look for corrosion or a broken bulb. If they all look OK, try disconnecting the other compenents one at a time. Whatever you do, don't try to "fix" it with a higher amp fuse.

Ok, thanks, it was that fuse, and the one I replaced it with was bad too, so it blew just as fast.
I bought a pack of 5 new ones for $2.13, and one fuse fixed it.
