Your tank should be a 16 gallon tank. That is what mine is, I have a 1993 also.
The Relay for what - door locks or something else?
If power windows in a 1993 Olds Cutlass Ciera don't work there may be a loss of electrical current. Check the battery and fuse. The power motor in the door may need replace.
Are they power seats in the front? My 1993 Ciera S has power recline - each switch is located at the front corner of the seat (near the door on the seat itself). Good luck!
The door lock/unlock relay is located behind the I/P on a 1995 Oldsmobile Cutlass Ciera. The relay is at the RH shroud just beside the center access hole
The Oldsmobile Cutlass Cierra window lift motor is located inside of the door. Each window is equipped with a window lift motor.
OPEN THE GLOVE BOX. YOU WILL SEE A SMALL DOOR TO THE Left. that's the hiding place of the fuses..
well 16 gallons maybe 18 if ya squeeze as much as you can get in there
On the turn indicator. Pull the turn indicator toward you until you hear it "click", about 1/4", then release.
I believe the 1993 Ford Explorer ( 4 door ) holds 19.3 U.S. gallons
Look on the drivers side door at the specs decal for that information.
To fix the outside door handle on a 1993 Oldsmobile Cutlass Supreme 2-door, remove the trim and access the mounting screws. Remove the nuts and disconnect the linkage rod by flipping the small clip and sliding the rod out of the handle. Reverse procedure for installation.
16.5 gallons for both the 2 door and 4 door model.
