On 2001 Crown Vic, radio lights are on, channels change,etc but no audio. Fuse issue or any other possibilities?

There are three fuse's for the instrument cluster , all located in the central junction box (fuse panel ) inside the vehicle ,under the dash !
Fuse # 14 a 10 amp , fuse # 23 15amp. and #6 15amp . Look behind right and left kick panel . But i don't think this is a fuse problem , gauge itself could be bad .

i had this problem with my 1999 jeep grand cherokee laredo with the brake lights it kept popping fuses right after the ignition was turned on try putting a higher amp fuse in place of the old one that keeps blowing then check for shorts to the starter and check grounds and wires and also the transmission issue check the fluid and then if the fluid is fine change the transmission filter the filter may have not gotten replaced when the transmission was rebuilt and may be clogged or dirty

With the outside temp being so low you can expect the heating in the vehicle to take longer to heat up and possibly not be as hot as if the temp was somewhat higher.

listed on the inside of the lid from the fuse box,

short in something the blinker clicking is the first sign of electrical failure in a car. any questions you can email me at [email protected]

have fuel pump checked i have known a bad fuel pump shorting out causing pcm fuse to blow.

where is the fuel pump relay on a 2001 crown vic p71

Go to your local auto parts store where you can purchase a Ford audio removal tool. It looks like a wire shaped "U" that is inserted in the holes on face of audio system ..Follow the directions for use , you will find it a pretty easy task with the correct tool..

The quickest way to find a short circuit is by putting a bulb in place of the fuse. Anytime the time the bulb lights there is a load. And if the load is a shorted wire the brightness of the bulb will give you a hint. So while you're at it, finding a 'short' is a quicky...keep your eyes on the bulb. gotcha!

Try checking all the grounds for the radio, over time they can weeken. If that doesn't work, put in a new ground wire with a heavier gauge, that should fix it. It sounds like a ground problem.

Good luck, Daniel
