The Radio is on, but the sound has left the building.
I have a 1996 Mercury Grand Marquis.
My problem is the radio is on but the speakers don't work. once in a while if you go over a bump the sound will work for a short time, but that about it. I looked up the stereo wiring on line. Do I follow the wires from the radio to find the problem? What do you recommend?

There may be more than one fuse behind the radio. I have 2, one for the display and one for the output section. It is possible the second of those has blown . To check you will need to access the
wiring behind the radio underneath the dqshboard
You need to take the plastic cowls off that cover the wiper arm linkage and wiper transmission to inspect it...cowl is held on with 3 Phillips screws near windshield and some one inch wide metal clips, take off the gasket that fits on top. If both are not working check the transmission where linkages attach, if one wiper blade is not working it is usually the drivers side where the nylon bushing that forns a ball/socket sort of connection fails due to build up of debris and the rusting of parts that follows, let me know if this helps.
This is a common problem with this radio. I purchased a used 2003 Grand Marquis and the radio stopped working after a few days. I checked all the usual problems such as faulty antenna and connections. I then looked on line and many others have the same problem with this radio. The only advice is to purchase a used radio from salvage yard the same as the one you have now or you can also go with a good aftermarket radio for around the same price as you are going to pay for a used radio. A used radio would require just removing the radio which is a snap, and then plugging in the replacement radio using the same connections. An after market radio will require adapters and splicing wires. I chose putting in an aftermarket JVC radio and I really enjoy the sound and being able to play cd/mp3's and my ipod through the radio.
make sure the speaker wires in the car do not have one side grounded.the output on the clarion is a floating output and cannot be grounded.the best solution is to look at the wiring on each of the speakers,and match them out to the ones on the clarion.the most common colr code is white front left,gray front right green rear left and purple rear right.each speaker has a plus and minus.mixing them up will result in the speakers being out of phase and result in poor bass performance.i would wire the wires directly to the clarion using crimp connectors.the first thing i would do is power up the stereo out of the car to 12 volts,and using a speaker make sure you have sound coming out.the yellow wire which is the clock/memory is a must to be connected to constant 12 volts or no sound can result
This is the only thing I could find, it is from a car audio site, hope it helps.
