I have a 97 nissan truck and the right blinker doesn't work can someone help me with this problem?
Thanks, Clint

Begin by replacing the bulb(s). Clean off any corrosion. Apply dielectric grease to base of bulb. If the problem persists, take a test light and check for power in each socket. Also use the test light to check all under hood and under dash fuses, if necessary. If the problem still persists, consider replacing the multi-function switch.

Where is the multi-function switch

It's the turning signal, high beam, etc. switch.

One of the wires was cut under the bed put it back together still nothing the tag lights are cut also did't see where to wire them back in, also the horn doesn't work probably isn't the same thing though

Got all the lights working but the front right turn signal it does have corrosion what is the best way to clean it off I tried scraping it with a knife and also sand paper? It still isn't working. The right rear bulb look melted inside change it out now it works. On to the next problems I discovered the belt squills when you first start the truck sometime lasting till after I shift out of second gear and the horn dosen't blow.

Either adjust or replace the belt--it may be old and dried out. Don't over-tighten, in order to eliminate belt squeal.

Try #240 abrasive cloth for corrosion.

On the horn I replaced the fuse under hood and the in cab is good what else could be causing it not to blow?

Jump the horn to the battery, to ensure it works. Horn contacts may be corroded, if it doesn't work.
