2008 Mariner Intermittent Hazard signal malfunction

Postby b4lines - June 30th, 2020, 8:39 pm

I'm having a reoccurring issue with my Hazard lights in my 2008 Mercury Mariner V6. The hazards will turn on by themselves at random times whether the car is parked or I'm driving it. It has gotten to the point where the switch will not always turn the hazards off when I press it. I've tried disconnecting the switch while the hazards are off and they still come on randomly after a time. I've examined the fuses in both the passenger fuse box and the power distribution box and the turn signal fuse appears to be working fine, I read that if the fuse was blown the hazards/blinkers wouldn't work at all. I'm out of ideas for what to try next, does anyone know what could be causing this?

It could be the hazard flasher relay is on its way out?

The hazard flashers are intrinsically involved with the turn signal switch. The same bulbs are used, and may be powered via a different source from the brake lights and turn signals.
If the switch in the column has some chafed wires, it can 'cross connect' and do stuff not in the original design.
I would remove the plastic cover and inspect the wires that get flexed when the column tilt is used. On F150s, there was a problem with the wire getting stretched. You cannot successfully stretch wire without causing problems. As far as I know.
Take a look, it's not hard to remove the cover, I think.

2008 escape doesn't have a serviceable flasher relay. It is controlled by "logic" in the SJB. IT is just a signal wire from the hazard-combo switch.
Maybe a bad Ground?

Ford part number 8L8Z-13K359-AA For about $30 from Rockauto or Ebay you can get a after market switch. Ford OEM is about $100. How does the E switch feel when you push on it? Soft and mushy or very positive and stiff? If it were me and I could not trace down the problem I would try a new switch.

Maybe a new switch is needed, or maybe a broken wire. Hard to say without troubleshooting. Maybe the parts Cannon can wait.
