Turn signals don't work but flashers do

[terrawombat]

My turn signals on my '88 pioneer no longer function properly. I'm not even sure when the last time it wad that they worked. The right blinker does work but blinks really slowly. The left blinker just remains on and never blinks. The hazards function as they should.

 

I've read a couple threads and this seems to be a common problem so I took some advice from them and here is what I've done:

 

new ford bulb sockets on both front turn signals

replaced flasher relay box

cleaned ground connection on inner drivers fender

 

still am not getting anything close to functioning signals. Any more tips?

the turn signals and flashers use separate flasher boxes. did you replace the right one? Try swapping them.

:agree:

 

Had the same problem recently on my boss's comanche, the 4 way flasher and TS flasher are seperate, swap them and see if it make the TS work if so, youre all set... get a new flasher, I think theyre 2 prong. You may still have socket problems, but this way at least youll know if you can get the TS to work.

Thanks fellas - I'll take a look at this after work! I was under the impression that the flasher relay was the big, yellow circular one. Are you telling me there are TWO of these on my fuse panel? I only recall seeing one...

[Pete M]

they are both the same size, but not necessarily yellow. might even be bare aluminum. IIRC, one of them is tucked up near the top of the panel.

Thanks Pete! I just took a look at a fuse block diagram for the '88 XJ and I see where it's at. I'll try swapping it out with a couple spares I have lying around. Thanks again!

[Pete M]

you could just swap between the 2 you've got. That would eliminate the variables since the flasher one is known to work.

Two other common problems (with turn signals) that I had were:

 

1) Corrosion at the connector between the engine bay harness and the front light harness.

 

2) Turn signal cam in the column was bad (Autozone sells the replacement in the 'Help!' section of the store - 2 cams for $9.00)

 

Good luck!

I swapped the two flasher relays on my fuse block and everything seems to be working!

 

Thanks guys! I'll pick up a couple spares just in case.
