Head lights wont turn off after turnning off car

Turn signal switch is bad.

some cars has a light interior adjuster and when turning all the way leave the interior light on all the time check that out should be around your light switch

Sounds like the headlight dimmer switch is defective. Remove the steering column covers and replace the switch.

Right now, I'm thinking the head lamp switch assembly has a problem? See the wire color in the top of head lamp, that is voltage, fuse protected, hot all the time. When problem is ongoing, you could use a test lite, check for voltage at fuse circuit?
The headlamp switch assembly is located on headlamp ground circuit. There could be a wiring problem, somewhere. I can only help with testing.

my durango does that too, its either the multi function switch (turn signal arm) or light switch, i haven't fixed it either

The relay for the headlight is stuck locate it and replace it. Get a cd repair manual on Ebay motors to locate the electrical component.

replace the headlight bulbs both should be replaced as a unit

Check switch itself likely it is worn out. also check lights for good ground and high beam switch. Most likely its the switch.

Need to replace the turn signal and dimmer switch.

They go bad frequently and arent hard to put in.

check headlight switch see if it has corosion or looks like it has been getting hot at wire conection
