i have a 2000 cherokee and my front side marker, and i guess fog light doesnt work when i turn my lights on but works when i use my blinker or hazards.. i bought brand new lights and it still does it.. what could it be?

 

Sounds like you may have a bad combination switch

Check your ground first.mine was doing the same thing in the rear.i has a bad ground connection.

 

Uh, I'm pretty sure he said his turn indicators and hazards worked fine so, not multi-switch. Also, the multi-switch doesn't have independent leads front and rear. If it were your multi-switch neither would work. Follow the advice of xjfan0310 and check your grounds... also check the harness connectors and other wiring that leads to that socket.

 

my turn signals and hazards will only work for about 8 seconds than they stop blionking and get stuck.. at first, they told me it could be my tailights itself, so i replaced them, than they say it can be my ground but ive searched for it and havnt seen any problems with that. i take it back and they tell me my terminals are bad and that could explain me not getting enough power to my lights but thats not it becayuse i JUST replaced those.. and i need to get it inspected asap

 

Did you check the hazard blinker relay? Also just because your grounds look good does not mean they are... Clean them even if they look ok...
