My 96 grand Cherokee bcm screen in flashing and I dont know why

the clicking noise could be a relay trying to latch or a security system armed either way you have to have your BCM(body control module ) checked, le me know what is the diagnosis

I THINK THE VIN IS LEARNED IN THE BCM WHICH MEANS YOU CANNOT USE A USED ONE

yes and no you can change your bcm and still have the same prob. you wires somewhere are grounding out

check the fan

no,this is a BCM (body control mudule) failure,have it check at a dealer.

the location of the bcm is at the passenger side glove box area

not a cheokee fan but i thik their was some changes made to the 98 model not sure but id go back with the part and ask it dosent sound as if it is the right part for the car hope i have helped you

remove the door switch, clean and reinsert. It switched ground to a black cable, which goes to the PCM.

you might need a set of torx or allens but as far as i know there shoulnt be any problem.

the info center was not working in my 96 jeep when i got it. it serves no major purpose other than a clock and to let you know when your doors are open. i replaced mine the part itself can be found at junkyards fairly cheap. i paid $65 for mine. and now i wish i had left it alone. constant annoyances and chimes.
