Turn signal issues on '99 Cougar

[1973 F-100 4x4]

A friend of mine's mom has a '99 Mercury Cougar that is having issues with the turn signals acting up when the headlights are on.
The turn signals work fine when the headlights are off, but they don't like to work most of the time when the headlights are in use.
I'm thinkin' possibly a short or a crossed wire?
Or maybe a bad turn signal switch?
Any help would be greatly appreciated.

What are they doing? Is it one side over another? Do they not work at all?

Not one side or other, they just don't want to work at all when the headlights are on low-beam.
On high-beam, they will only work if you hold down the lever and wiggle it for whichever side you are trying to use.
When the headlights are off though, they work fine.

I'd go combination switch.

The car's headlight switch is in the dash, not turn signal mounted.
However, the high-beam switch is on the turn signal lever.
Is this the combination switch you are referring to ?
