Hi my name is john.
On the rear wiper read this.
The rear wiper system on the Grand Cherokee operates through the liftgate and rear window ajar switches which act as lock outs to prevent the wiper from operating when the liftgate or rear flipper window is open. A situation can arise where the liftgate or rear window is ajar and the driver may not be aware of it. On Laredo models, not equipped with a Vehicle Information Center (VIC), if the dome light override feature in the cargo lamp is activated, the liftgate can be ajar with no operator warning. This situation can and has been reported as an inoperative or intermittent rear wiper operation. If complaints are received indicating rear wiper operation problems on these models, be sure to explain the operation of the system with the ajar switch and dome light override prior to attempting repairs

SUBJECT: Radio Diagnosis
DATE: Feb. 16, 1996
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:
- stations changing with no switch input
- radio memory presets not working properly
- volume changes with no switch input
- switch buttons taking on other functions (volume switch changes stations)
- CD player skips tracks
- remote switch inoperative
On the seat do you have memory and heated seats?
