Disconnect the negative battery cable.
Remove the steering wheel, and then remove the steering column covers.
Remove the turn signal and wiper switches.
Disconnect the ignition switch wiring.
Remove the clamping washer, spring and contact ring from the steering column, and then remove the lock housing up off the column tube and steering column.
Remove the ignition switch mounting fastener and remove the switch.
Installation is in reverse order of removal noting the following:
Press the contact ring, spring and clamping washer onto the steering column using a properly sized and sturdy metal pipe or tube. If after installation of the clamping washer, the steering column is not projecting out far enough, pull the steering column out further.
Usually it is a bulb because it takes all 3 or 4 to make the flasher work. Not all bulbs have to work for the emergency flasher. If all of the bulbs are in fact good, it could be the turn signal switch. On rare occasions the flasher is the problem
GM multi-function switches (the switch on the steering column) are VERY involved to replace (unlike Dodge and Ford)! in most cases, you have to tear half the steering column apart to gain access to its mounts. You are better off taking the car to a mechanic if that is the case.
SOMETIMES THE FLASHER IS IN THE FUSEBOX , SOMETIMES IT WILL BE UNDER THE DASH NEAR THE STEERING COLUMN. THERE ARE TWO FLASHERS ONE FOR TURN SIGNALS & ONE FOR HAZARD LIGHTS. THE TURN SIGNAL FLASHER MAY BE YELLOW & ONE OF THE WIRES WILL BE PURPLE. YOU CAN TURN ON THE HAZARD SWITCH IF THEY WORK YOU CAN LOCATE THAT FLASHER BY THE CLICKING SOUND & ELIMINATE THAT FLASHER & LOOK FOR THE YELLOW PLASTIC ONE. A SMALL MIRRIO MAY BE HELPFUL UNDER THE DASH.

Well this is a long process but ive done quite a few of them. The first thing is to remove the airbag if your suv has one. Im pretty sure that in 1990 they didnt use them in this vehicle.The first step without an airbag is to remove the steering wheel. You will need to remove the horn cover to access the 21/22mm nut holding the steering wheel on. Be sure to not break the wire going to lthe horn switch inside the cover. push in and turn left on the plastic locker that holds the wire into the column and remove it. Then, after removing the nut holding the horn on, u must use a steering wheel puller to remove the steering wheel from the shaft.[normally auto zone will rent these pullers].read the directions of the puller to remove.then there will be what is called a clock spring assy if you have steering controls for the radio. If not the steering lock mechanism will be next. This requires a 90degree angled pick and another special tool to press the lock mechanism down off of the hog nose ring holding the steering lock ring in place.[possibly at auto zone again]. Once again read the direction of use for that special tool. Now you are almost there.Remove the hazard switch phillips head screw.Remove the phillips head screws holding the turn signal assembly onto the steering column[should be four]] and the two holding the lever onto the switch.Remove the drivers side lower dash panel to access the wiring block that has the rectangler conector end of the turn signal assembly attached to it. normally you can use a small screw driver to pry it out of the wiring block. To remove the old turn signal assembly just cut the wires from it at the top near the working part of the assembly .The next step is the hardest because you have to route the new turn signal wiring down through the steering column like the old one was.Tke some electrical tape and attach the new turn signal wiring to the old wiring and guide it down the column as your removing the old at the same time. Make sure to have the rectangler portion of the new wiring at the right angle when taping so theat it fits going through the steering column....Now just reverse this procedure to finish the install....Note that if you are not careful, the loose turn signal lever will allow the high/low beam switch mechanism to fall out of the actual high/low beam switch attached to the steering colmn.there are a couple more things like a flex type washer and the white horn mechanism to remove suring this removal process. Just keep all your parts in the order removed and all should be well....told ya it was long!!! If you have any questions, just e-mail me and i will help more if i can....Hope you have much luck with this job, Ken..firstname.lastname@example.org
The actual switch is under the steering wheel. You have to use a steering wheel puller to get the steering wheel off. You also need a special tool to compress the shifter locking plate spring. Then you can check the switch to see if it's working. I have pasted the instructions below if you want to go at it. Let me know if you have questions.
The following procedure requires the use of the GM Lock Plate Compressor tool No. J-23653 or equivalent.
Disconnect the negative battery cable.
Refer to the Steering Wheel, Removal and Installation procedures in this section and remove the steering wheel.
If necessary, remove the steering column-to-lower instrument panel cover. Disengage the electrical harness connector from the steering column jacket (under the dash).
Using a small prytool, insert into the slots between the steering shaft lock plate cover and the steering column housing, then pry upward to remove the cover from the lock plate.
Using the GM Lock Plate Compressor tool No. J-23653-A or equivalent, screw the center shaft onto the steering shaft (as far as it will go), then screw the center post nut clockwise until the lock plate is compressed.
Using a small prybar, carefully pry the snapring from the steering shaft slot.
If the steering column is being disassembled on a bench, the steering shaft will slide out of the mast jacket when the snapring is removed.
Remove the GM Lock Plate Compressor tool No. J-23653 or equivalent, and the lock plate.
Remove the multi-function lever-to-switch screw and the lever.
To remove the hazard warning switch, press the knob inward and unscrew it.
Remove the turn signal switch assembly-to-steering column screws.
Lift the turn signal switch assembly from the steering column, then slide the electrical connector through the column housing and the protector.
If the steering column is the tilting type, position the steering housing into the Low position.
To remove the harness cover, pull it toward the lower end of the column; be careful not to damage the wires.
To remove the wire protector, grab the protector's tab with a pair of pliers, then pull the protector downward, out of the steering column.
If it is an auto trans with column shift, that switch is on the steering column, above the brake pedal, close to the floorboard. Might need to lower the upper end of the steering column where it bolts under the dash to get to it.
