1993 Chevy Cavalier Turn signal slow

Replace the turn signal flasher relay, behind the dash on the right side of the steering column support.

where can i find the one that i need?
do you have a diagram or picture of what i should look for?

No I dont have a picture, but they are normally silver and round, but can be yellow plastic, when you remove it it will have three prongs on the plug in side.

do you know where i can pick one up?
will any auto parts store have it or is it special?

any parts store.

i found directions on another website. here is what i found i was able to complete the job in about 1/2 hour. i did not remove the silver box as it would not come off. You'll need a 10mm short socket or ratcheting wrench(ideal because of small space) and a 6mm socket(use an extension here to save your back). Remove the plastic panel covering the base of the steering column (3 x 6mm hex screws w/washers, left, center and right). Don't confuse this with the small plastic box immediately around the base of the steering wheel. Remove the plastic panel carefully so as not to break off the retaining tabs toward the top. On the right near the base of the exposed steering column you should see a silver electrical box about the size of a box of matches with a wire plugged into the high end. There are 2 10mm hex screws holding it to the frame. Remove them and move the box out of the way. Avoid unplugging the wires. Lie on your back and look up into the area near the column and locate the flasher. It should be on the left up high as viewed from this position. There is a retaining clip that holds it in place. Slide it off the metal tab and it should be easier to fish it out. Replace the flasher and then reverse the procedure used to get at it. Some engineer had fun creating this configuration!! Allow an hour. here is a picture of what the flaher looks like.
