I have a 97 Grand Cherokee Limited with the VIC that displays warning messages. Whenever my key is in the accessory position, I get the rear lamp failure message on the VIC. Whenever the key is in the run position, I do not get the message though. I have checked all my lights many times including the 3rd brake light. I want to know what the problem is and what would make the message come up when the Jeep isn't running and not come up when it is. I do not know if this is related or not, but whenever my lights are on, my blinker blinks really fast sometimes.
