I have a 98 Frontier and currently the Turn signals nor the Wipers will work. I also have to "jump" the clutch interlock relay in order for it to start.
Here is a little bit of background.
The battery started to lose charge so I replaced it. The new battery died as well and the truck would not crank. I checked the inside cab fuses first and did not have power to the wipers or signal fuse.
No noise at starter. I realized then that maybe it was the starter so I replaced it . After replacing the starter the truck would still not crank. I then thought maybe it was the alternator and I replaced it as well.
I checked for continuity of my battery fuses link and all had power. Both sides of my engine fuse box is getting power. I replaced the clutch interlock relay and still nothing. I then put a wire "jumped" the clutch interlock relay and the truck will start but I don't have wipers or signals (hazards do work).
I also thought maybe it was the ignition so I replaced the ignition switch in the column.
The truck still wont crank unless I jump the relay, and even then my wipers nor signals work.
TLDR
I can only crank if I jump the clutch interlock relay (I've tried numerous new ones)
No power to inside fuse for wipers and turn signals.
Replaced fuses, alternator, starter, battery and ignition switch.
Here is a pic of "jumping" the relay
