Ok guys got a strange issue with the hazard lights on my GTM Coupe project. The hazards lights all work fine when switched on but the main beam warning light flashes instead of the direction warning ones.

By a bit of trial and error I found that if I disconnect the wire from the back of the hazard switch which feeds the right hand indicators so only the left side is flashing, I get the correct left direction light flashing on the dash. I've tried disconnecting each of the right indicator lights individually incase it was a wiring issue with one of them but no luck.

Any suggestions?

Forgot to mention, indicators work fine and the correct direction light shows up on the dash when using them. I've also tried replacing the hazard flasher unit.

I did have a similar issue with my rear lights a while ago and it turned out to be an earthing problem.

what loom are you running?

Thanks for the suggestions, I have found the problem! there was one black wire on the back of the warning light cluster not connected to anything, earthed that one and now all working correctly

Ye I'd have thought bad earth. Glad you sorted it
