Need Help

I have a friend that has a 1998 Ford Taurus and the radio has been acting wierd. When the car is in drive or reverse the sound cuts off but the display stays on. When the car is in nuetral or park the sound comes back on. Has anyone ever seen or heard of this problem before. All the wires look factory and not messed with. I haven't checked the fuses yet but didn't really see that as causing the problem. Any help would be appreciated

Take the radio out of the dash, put a meter on the harness, there will be a couple of positive 12v leads, test each one with the car and park/drive, see if there is any fluctuation. Confirm that the ground connection stays when the shifter is moved.
Turn the power to the car off, and check continuity of the speaker wires to ground.

Let me know what that gets you.

I'm assuming you have a multimeter, if you don't, i'm sorry.

Thought about that but all the sound cuts out so I figured each wire would do the same thing when I put a volt meter up to it. Here is what I found out on the Ford Taurus Occasional problems on this vehicle are failure of the Transmission Range (TR) Sensor and the Door Ajar Switches. The symptoms associated with failure of the TR Sensor are loss of sound from the radio, loss of power window operation and loss of power steering operation when the car is shifted from park to reverse and/or drive. The cost to repair the TR Sensor is estimated at $40.00 for parts and $39.00 for labor. The cost to repair the Door Ajar Switches is estimated at $22.00 for parts and $45.50 for labor per door and can range from one to four doors. All prices are estimates based on $65 per flat rate hour and do not include diagnostic time or any applicable sales tax. Hope this helps if you ever run across it I did also find where its located and how to fix it. It is located on top of the transaxle just below and to the inside of the master cylinder. It is fairly easy to change. Remove the shifting linkage, remove the wiring connector and remove 2 mounting bolts. Installation is just the opposite. There are marks that need to be lined up when the transaxle is in neutral. Look closely at the new part and it should have the marks already lined up. Part is generally well under 50$.
