Check your fuse. Usually the manufacturer has the dash lights and the tail lights on the same circuit.
I had the same problem with my 1997 Grand Cherokee and it was the dash mounted automatic light switch. The problem was also solved by turning the headlamps on manually.
Check fuse for tail/parking/dash lights
under the dash right hand side.
Short
Your 1996 Jeep grand Cherokee dash lights probably keep flashing and dimming because of a loose or corroded ground wire. The ground wire might be getting contact at times and at other times not getting contact.
this happened to mine it was to burnt out wires behind the dash
the evaporator inside the heater box behind the dash most common
How do you turn on dash lights 1993 mercury grand marquis
Yes 93 to 95 are the same
i have a 1997 grand am 3.1 liter motor no spark or dash lights or fuel pump pressure
If parking and dash lights work: Maybe bad bulbs (double filamented) Bad socket? Bad ground circuit?
If the 97 is set up like the 96, then the same 15 amp light blue fuse that controls the tail lights will also control the dash lights. On the 96 this fuse is # 17 in the fuse panel behind the battery.
