i can change my flasher for the turn signal?

Until others chime in, what I remember about the flasher units it that it'* a simple unplug and replug in unit. There are usually to flasher units. One for the turn signal and the other for the emergency flasher. In the ol days, the turn signal was a 2 prong and the emergency was 3 prongs. Unless the flasher was completely gone, I used to turn it on and listen in order to locate. Sometimes they were part of the fuse panel there easy to locate (if you knew where the panel is.

May we ask why you think you need a replacement?

i need a replacement because my turn signal doesnt flash when applied. the 4 way flashers work fine though....

Have you checked to make sure that all of your bulbs, front and rear, are working?

yes, all of my bulbs work.
