Left lights out Any ideas?

[kbfoster01]

My front and rear left turn signal, left brake light and left emergency flasher stopped working on my Coach and toad. I can hear the blinker making normal noise but no light. The schematic shows only one fuse for the lights both right and left together and that is good. They work fine on my toad when I unplug it. I am driving a 2004 country Coach intrigue suite pulling a Jeep Wrangler. Does anyone have an ideas as to where I should start? Thanks

On my old rig, the front left and rear left turn signal is grounded at the same point.

I suspect you have a dual filament rear bulb so the ground may affect the hazard and tail light bulb.

Try finding and testing the ground connection for your MH left turn signal?

Thanks Dean but I can’t seem to figure out where the ground is located. Just a bunch of wires running up to run box under drivers side. Any clues to find the ground.

Thanks!

Looking at my coach's exterior lights schematic, the front and rear lights have ground wires (all are green) that appear to go to separate ground bars. So, perhaps try to trace green wires to one or more ground bars.

Did this problem first crop up when you were towing? If so, just thinking out loud, you might want to check your tow board and see if any of the fuses there have blown.

The ground for the fuses in the front run box is a single wire at the bottom of the fuse holders. If that fails, all that stuff will fail.

I have grounding bars on both sides of my engine compartment that service different components.

If you have the rig's Owner manuals mine has a schedule of the wire numbers in the coach in a "from/to" format.

Although, ground wires are not displayed on the wire list. They are typically displayed on the schematics.

Could be a bad bulb as well
Remove bulbs clean bulb socket from any corrosion and put in new bulb
Had a similar issue on our 04 intrigue and that was my issue
Also heard ground issue can occur on clearance lights

Start with rear tail light first was an easy and inexpensive fix
