I hope someone answers your question because I have the same car with the same problem.

I already had a connector it the car for trailer lights. It used to work & seems to still be working. But when Haul plugged in trailer lights to it, our turn signals stopped working. The connectors from the trailer were real ratty; I wouldn't be surprised if they hooked up something backwards. They also had to run a separate ground wire to get the lights on the trailer working. I think they had the turn signals working at some point when they were hooking it up.

Symptoms (all started when trailer hooked up):

  • Turn signals completely dead. No lights, no flashing, no turn indicator lights on dash board.
  • 4-way flasher also completely dead.
  • Alternator light on dash & brake warning light on dash both on.
  • Problem same whether trailer hooked up or not.

Things that still work:

  • Brake & parking lights work fine on car & trailer. I repaired the connections on the cable coming from the trailer and it seems to be wired correctly. I tested the trailer lights with a spare battery and they light when they should.
  • All fuses visually look good (both the ones next to driver & the ones under hood).
  • UHaul connector installed on car has built in indicator lights (wonderful feature!). Lights come on when they should for parking & brake. But they don't come on for turn signal, which is no surprise.

I can't find the flasher (if there is one). I can't find my owner's manual. I can't find any clues or fuse diagrams on the Web. (Google has a lot of strange Russian websites that don't have anything to do with the car-annoying.



Richard, did you ever find out a reason for this? I have exactly the same problem.


Possible solutionTry the hazard switch

this cuts out the supply to the indicators to prevent overloading the circuit

if the switch has gone faulty the indicators do not normally work.

locate it by turning on your emergency flashers and listening for the click. once you find the unit that is clicking, you have found the flasher unit
