How do you change the cluster in a 1988 Cadillac Sedan DeVille?
You have to remove the dash upper pad and the lower dash trim
under the steering column. The shift indicator cable clips to the
steering column. You dont need to remove all of the wood trim
around climate control, etc. Only the small section under column
and the plastic lower panel that is dash colored.
There are 3 dash pad screws in the defroster grille, one in each
a/c vent. (carefully pry the 4 vents out from each end) There is
also one, if not two screws going straight up into the dash just to
the left of where it says "cadillac". They are accessed through
holes in the top of the glove box liner. The screw requires a 7mm
or 9/32 socket on long nut driver or ratchet and extension. Be
careful disconnecting the in car temp sensor directly behind the
word "cadillac". Once dash pad is out of the way there are 3
cluster screws and 2 holding a black trim bezel located directly
under the cluster face. The cluster has to tip towards you to in
order to allow the PRND321 indicator to clear the dash. Be sure the
dental floss like cable is unclipped from the steering column
shifter collar first. This applies to all 1985-1993 FWD Deville,
Fleetwood, and 60 Special.
