Do the hazzards work?
Customer: replied 8 years ago.

Ok, when you turn on either turn signal, do the bulbs light but do not blink OR do NO lights come on at all?


Do the brake lights work ok?

Customer: replied 8 years ago.
They do not come on at all. Brake lights work fine. No indicators on dash either for turn signals.
You mentioned fuses ok and you can confirm 100% the fuse labled TURN SIG is ok? Just doubkle checking before i go on. thanks

yes 7.5 volt fuse, continuity checked OK out of circuit.

Thanks. Most likely you have a bad Turn/hazzard flasher. Yes, I know the hazzards work but.. this flasher is not like most you have seen. It is a solid state , mini computer flasher and the hazzard/turn circuit is seperate inside it. The other item could be the hazzrds switch as the turn sig feeds through it. I have not seen the hazzard switch be the problem but have seen the flasher on many occations fail./


It is #4 in the left side diagram

Where is that located on the vehicle so I can replace it.
That was the picture i sent of the fuse relay box. It is # XXXXX in the picture. Same box as the Turn fuse you checked.
