2003 grand marquis radio am does not work

I DON'T KNOW. AUTO WRECKER REPLACEMENT MAY BE LOWEST COST.

So, maybe it's time to get away from the used junk and buy a new aftermarket radio.

I would say the most common problem is a bad antenna.

just a thought make sure your antanna hasent come unplugged if it hasent you most likely have lost the fm band channels in you radio. i hope this helps it was just a thought

Buy yourself an aftermarket antenna and install it. Do not get a power retractor, nor one with a ball on the bottom, just one of those simple 31 inch rod units.

You will most likely have to pull a fender liner to mount it and fish the cable around to get it to the back of the radio. Try and avoid an extension cable. A local car stereo store could do this cheap in about an hour. Retracting antennas, in the windshield antennas just do not work.

You have an antenna problem if this is just on FM

make sure the antenna is plugged all the way into the back of the stereo

Half volume is good enough. (and a cheap fix)

I would first try to clean the scan button with air can and then very small amount of WD-40 then air can again, try and press and pullout button after this

check the back of the radio, make sure than the antenna, connector is plug into the radio, if it is, then replace the radio.
