I recieved my grandfathers truck about a year ago. it sat in the driveway for that time until here recently. i drive an expedition daily but really hadn't thought about driving the isuzu. anyway it is all good and runs well but when i go to use my turn signals they wont work. the hazards work perfect, when i am to try the turn signals sometime it will buzz at me and others it will make the normal ticking noise. any ideas?

 

replace the turn signal relay alot of times only part of it will be working and it will still have functioning hazards and not turn.
