Both Turn Signals On Dash

[kq.echo.413]

Ok I have been working on my 89 pioneer comanche 4.0..I have changed the headlight switch regrounded the dash harness and checked all lights in the cluster.But I still have both turn signal on dash lighting up like there is a issue somewhere else.Any ideas would be helpful..

All the time? With lights on or off? When did it start?

Replace both front turn signal sockets. Your sockets are bad, and the lights are grounding by backfeeding through the dashboard.

Nitro..

I just bought this one .it had lots of issues but I have narrowed it down to just the to lights on the dash. It only happens when I turn on my head lamps

I will try the signal buckets ..or can I reground them to chassis

what eagle is telling you is very common and I am sure will fix your problem. No re ground needed just new sockets.

Won't help. The sockets are bad internally. Replace.

 

Been there, done that.

 

And don't even think about junkyard sockets. This is a known issue with XJs and MJs -- why replace one 25-year old part with another 25-year old part that has the same problem? There is a socket marked for some Ford vehicle that's usually available in the Dorman "HELP!" parts line at all the parts chains that fits the XJ/MJ light housings perfectly. Unfortunately, I don't remember the part number.

:agree: 100 % Been there done that. Definitely support the use of NEW front turn signal sockets.

Also, whenever you are doing an electrical repair, it is a good idea to break out the soldering iron and shrink tubing instead of relying on crimped connections. It takes a wee bit longer, but the repair won't fail because of a corroded or loose connector later...

Thank you guys... I am on the hunt for light sockets..I will keep you posted

I had the same issue. Both dash arrows light up when headlights are on. I changed the sockets and problem solved. Signals and dash lights work exactly as should.

I did find metal bucket light sockets that would fit at my local parts store.. The lights work perfect now ..thank you guys for the knowledge
