Here is my issues. I lost my marker lights front and rear. Headlights still work, but when I turn the vehicle off the lights stay on. I put the key in and turn it forward they turn off. Brake lights work, hazards work, turn signals work. I am lost. All fuses are good. It all worked 2 days ago.

 

not sure about your marker lights but what package is your xj? because i have a 1990 xj laredo and it has auto shut off headlights from the factory takes em about 30 seconds to a minute to shut off after i turn off the key if i shut them off before a kill the key they go off instantly
