Many times fuses look like they are still good but have hairline cracks in them. Look in your operator's manual at the fuse panel chart. Replace the fuse or fuses that control these things with new fuses of the same amperage.

01 acura cls radio, and both acc. outlets dont work. Fuses are good key is on

There is a power control panel under the hood on the passenger side with big fusses. Either on of them is blown or the power control module is faulty which is also located in the same panel as the fusses.

Wont start, no headlights, power windows, horn, heater controls, or guages. Taillights work and doorlocks work as do all the interior lights

I think I would suggest checking the fuses again.
There are two cables coming off the positive battery post. You would need to trace those cables to find out which fuses are dead and alive rather than just blown.
I'm showing a 50amp fuse and a starter relay in the power distribution center near the battery along with a dozen or more fuses for other main circuits. One of the circuit bars could be damaged under the fuse box.

I recently had a after market stereo, Amp and bass box installed now my AC,Heater and vent blow out of the top dash defrost vents and not the ones facing the driver and passanger. I checked all the fusses...

Check for a vacuume leak, a small broken hose around the radio or heater controller or around the engine bay. Those snap real easy when they get old and maybe when they ran the wire from the battery or around the radio one got pulled out or snapped. Good luck..

Infinity modulus problems with car radio for 2005 Chrysler Crossfire. No sound

If the radio works the two fuses for it must be OK. 15A fuse 23 is the source of amplifier power. The amplifier is probably tucked away near the radio

Turn signal do not flash or iluminate or work

Check the relay fuss near the fuss box, also check the fuss itself. If this will not work check your wiring harness and lead wiring lines that feeds the tail lights. If the tail lights work along with the brake lights its not a wiring issue its either the fuss or the signaling arm drive relay box on the steering. Also check your 4 way fuse as well

best way to do it is to get yourself a pair on needle nose pliers and start pulling fuses one at a time.
