sounds like a constant 12v issue, usually not fused independently.

1 thread wasn't enough?

Try to fine them underneath the steering wheel, and look up your owner's manual. If you can reset clock and radio, the fuses should be OK, there is something else wrong.

is it an aftermarket stereo? and is it the clock on the stereo or the clock near the heater controls that keeps loosing memory?

and for the record.. if it turns on the fuse is working correctly. so count a bad fuse out of your list of things that could be wrong.

there are basically two types of power in a car. constant and switched. sounds like your stereo doesnt have the constant wire hooked up correctly. if its only switched then u will loose all memory (presets, clock, etc) when you turn off the ignition.

now im going to assume your stereo is aftermarket and all the problems u are having are with the aftermarket stereo only. if you are mechanically inclined to remove the stereo and inspect the wiring this is what needs to be connected (assuming u also didnt use the appropriate wiring harness connector)...

the stereos red and yellow wires are your power. yellow should be constant with the battery and red should cut out with the ignition (switched).
your yellow wire needs to be connected to the cars blue/yellow wire (blue witha yellow stripe) in the stereo harness.
the red wire, if i remember correctly, connects to the gray wire (switched on and off with ignition).

make sure u use appropriate connectors (NOT ELECTRICAL TAPE!!!).

if u are unsure please take it to a professional to sort out. nothing is worth u trying to fix and ultimately causing more damage by not knowing what you are doing.
