Hi all, new to this site and I would appreciate some insight. I just recently bought a 1990 Isuzu truck it has 97K miles on it and it runs great. Recently the turn signals do not work and the hazards do not work also. I checked the fuses under the hood and under the steering and they are fine. Can anyone give me an idea where I should check next?

Thanks

 

I had this problem before, what I did was just remove the turn signal switch assembly, disassemble the switch, clean it and then reassemble it back. That solves the problem for me. But as for you, you said your pick up truck is just brand new so this won't be necessary but still check it. Maybe you need to replace the turn signal relay.
