Thanks for responding.
The "FM" is the radio. It works only after warming up for about 10 minutes. It has to be on FM all that time to come on. The AM portion works fine. Also the rear windshield wiper doesn't respond but will come on intermittantly by itself..Als the seat position only works sporadically. The information center below the radio only works from time to time. I suppose it has to be electronic, but what? Also...I forgot to mention, the left speakers do not work. Could that be related to the amplifier? Are there any circuit boards that could be replaced?

The condition is usually accompanied by a loud popping noise which occurs when the volume control knob is turned. The radio will return to normal operation after the volume control knob is turned.

Refer to the Warranty Policy and Procedures Manual for the repair center locations in your area. Make sure to clearly communicate the symptoms to the repair center. The symptoms should be stated as: "1996 ZJ Limited RBN radio with an intermittent no audio output condition due to interference between the radio and the Memory System Module".

Some vehicles are equipped with remote radio switches. These switches or wiring (clock spring) can cause symptoms that in the past may have been internal radio problems. If radio symptoms occur that involve any of the remote radio switch functions, be sure to check the switches and clock spring prior to sending the radio out for repair. Remote radio switch diagnosis can be found on page 8F-5 in the 1996 Grand Cherokee Service Manual.
Some of the symptoms that could occur as a result of malfunctioning remote switches are:
The heated seats work..
The seat heaters work. The other functions of the seat work properly. The things that don't work are: 1- memory seat
2- back window windshield wiper
3- information center below the radio.
all (3) of these things will start to work for no reason. Then they won't work for maybe a month.
The dash lights will work if I press anywhere on the guage panel or the light switch itself.
When the dash lights do work, they generally will stay on until I turn off the vehicle.
Is there anything that would cause the dash lights, the seat position settings, the rear windshield wiper, or the information center to only work from time to time?
Is there a ground, a circuit board or anything you can think of. Its driving me nuts.
