Changing turn signal switch on 93 oldsmobile cutlass supreme

I need instructions on how to change out the turn signal switch. we have gotten everything off where we can get to it but there is a bar in the way of the clip and we cannot get the old one out to replace the new one. the space is to small to remove the old one. Also the break lights do not work. we have replaced the bulbs. any suggestions on that would be helpful also.
Thanks much

    Have you p[ulled your steering wheel? When you say bar, are you to the ignition switch, or are you stuck at a plate that requires a special compression tool to remove? You have defeated the air bag...right?

Removing the turn signal mechanism from the steering column is easy and can be accomplished in under a half hour. First you should remove one of the battery cables as you should have no power available when removing or installing the wiring harness.then remove the front of the steering wheel.These usually just snap on or off. Remoce the steering wheel using a small puller once you have removed the nut. . Usually available for aroung $10. Now that the signal mechanism is exposed you can wemove the plastic horn ring and also the 3 screws securing the mechanism to the steering column. Leave the mechanism on the colum for now. You can however reomove the screw that holds the lights, wiper and turn signal arm and let it hang free as there is no need to replace it if everything is working. Next you have to remove the two panesl under the dash immediately under the steering column. Tracing the wiring from the turn signal to where it enters a wiring block. This block has all the wiring from the turn signal, lights , cruise control and turn signals all on different modules. You are only concerned with the module from your tirn signals. To remove this module you have to separate the block by using a small ratchet and a 7mm socket. once the the bolt holdingb the block has been completely loosened the inner block can be oulled away from the outer block. Now the module containg the turn signal harness can be removed from the inner blosk and now you are close to removing the harness but first there is a plastic sleeve that protest the wiring as it passes along the lower part of the colimn. Squeezing one end of the sleeve you can push it out until it clears the colum. it can now be opened and reomoved from the harness. Now you can reomve the mechanism from the column and ease the harness up throught the steering solumn being careful to guide it through. The last two wires on the module , a beize and green wire that ties internally to the column will need to be cut and spliced into the new harness. Using the reverse proceedure you can install the new turn signal. First time may take a hour or so . One gets better with practice. Good luck John

Where is the turn signal flasher located on a 1987 cutlass supreme. I have no turn signals and have changed all the bulbs. Help!

The flasher is located on the fuse block. The other thing that may be wrong could be the actuall switch for the turn signals which is located inside the steering coloum.
