Installing New Seat Leather Kit - 1993
Part I - Removal
To remove seats from the 1993 Allanté, move them all the way up and all the way forward. On the passenger side seat, it will be necessary to remove a stop and the rear of the seat track. The stop is held in place by one 10mm head bolt.
There are two Torx head boles holding down the rear of the seats. T-47 bits feel loose, and T-50 bits are tight. We have had best success by broaching (hammering in) a T-50 bit and then removing the two bolts (1).
Lift up the back of the seat, and then pull the front tabs out of the slots in the floor pan (2).
There are 4 plugs that muse be disconnected under the seat: one large one into the seat memory module, and then three smaller ones (color coded white, black, and blue) over toward the console. All four have release tabs (3).
Once the seat is out of the car, the first step is to take off the seat switch panel by removing three Phillips head screws (4).
Pushing down the release tab on top of the connector disconnects the main switch wiring (5).
The lumbar switch wiring must be disconnected. Pull the wiring out and continue to pull gently until the connector is exposed. Lift up on the release tab on the connector and disconnect the wiring and the seat switch panel will come free (6).
Lay the seat on its side. Unclip the plastic · "U" channels at the bottom of the cover that hold the seat bottom cover to the frame (7).
Peel up the cover from over the hinge on one side, and remove the two bolts that hold the seat bottom and seat back together. On early 1993 models, it will
be necessary to put a wrench on the jam nut on the back of the bolts. On late 1993 models, the nut is welded to the back of the tube, so a wrench won't be needed (8).
Locate and unclip the plug in the wiring to the lumbar motor. There is also a cable tie that muse be clipped so the wiring to the seat back will come free (9).
Remove the 15mm nut that holds the seat belt buckle to the seat base and remove the buckle (10).
Peel up the other side of the bottom cover around the other hinge, then remove both bolts and pull the lumbar motor wiring free. Pull up and remove the bottom cover from the padding on the seat frame. Velcro is attached into the padding. Carefully
separate the Velcro so the cover will come
comp etely free (12).
Next take the cover off the rear portion of the seat. Lift up on the top of the seat back release and pry it off (12).
Separate the snap channel at the bottom of the seat back and pull it completely apart (13).
If you have a good relationship with a local Cadillac dealer, try to borrow their Kent Moore tool #J-39509 Headrest Removal Tools (14).
Insert the tools down the face of the headrest shaft to pry out the retaining clips (15). If you cannot borrow the tools, skip this step and headrests will be
The secret to getting the cover off the seat back is cutting two pieces of cardboard both, slightly smaller than the seat back ( 16).
Run your arm up inside berween the cover and the padding. Break the Velcro connection berween the cover and the padding. Then insert one piece of cardboard between the padding and the cover to keep the Velcro from reattaching (17).
Next run your arm up into the rear of the seat back to break the Velcro connection, then insert the other piece of cardboard on the back of the seat in between the frame and the cover (18).
Stand the seat back on end, and pull the cover down over the frame. The cardboard will keep the Velcro from reattaching as long as it stays in place (19).
If you could not remove the headrests earlier, pull the covers inside out over the headrests, exposing the shafts (20).
Find the retaining clip and lift it with a small screwdriver so the headrest shafts can be pulled free, one at a time (21).
Once the cover is completely free, remove the two headrest shaft bezels so they can be reused on the new covers. Pry the plastic washers off the back and remove the bezels (22).
