The stereo in my 95 town car will come on but there's no sound. it will work sometimes and other times it wont

if it sounds like a vacuum leak then you will have to find the leak first. then go from there.

check starter,alternator
or any loose wire on battery

Sounds like the slip ring in the wiper motor has a strip missing from it,if so you need a new wiper motor,parts for wiper motors are next to impossible to find.

Coils replaced?

Turn on radio on half and get in the back seat and listen for distortion and if that dont work turn off the key unplug one speaker at a timeuntil you find it the wire are in the trunck connected to the speaker.Listen then not exceeding the power on the speaker and you wont need to turn it up that loud you will notice whats blown quickly.

Hi have you tried using the settings on the stereo that controls the balance from front to back and side to side if you have changed these settings without knowing then the stereo output might be in the possition for the one side.
If after doing this you still have the same problem then i would remove the stereo and check all the wires are secure if they are then you need to remove the casing for the side speakers and check the wires for corrosion and make sure connected properly.

Usually the speakers wont just suddenly stop working if the problem was with the speaker then you would have noticed over time that the sound was distorted or would have sounded crackley from the speakers.
If this is not the case then check the speaker balance on stereo and then check wires.

Let me know how you get on or if you need further assistance ok

Where is the amplifier located on a 2002 Town & Country? My stereo seems to be working, but there is no sound coming out of the speakers.

CHECK THE FUSE OF THE ALTERNATOR OR CHECK IF THE ALTERNATOR IS CHARGING

Its sounds like your engine wormed-up.
