My friend has i believe a 93 jeep cherokee, the problem is his blinkers won't work, the bulbs are all fine. When he tried to turn on either side, no lights blink and in the dash the lights don't blink either, but if he puts on his hazards they all work. Any input will be appreciated. Also we checked all the fuses and they are all fine. Any input guys?

sounds like a bad turn signal flasher. The turn signal and hazards run on seperate flashers. It's located under the instrument panel, drivers side, it'll be a round, & silver in color attached to the fuse block.
