heck the fuse first, then the switch.
I own a 2005 jeep Cherokee my headlights on the passenger side is not working changed the bulbs & they are still not working.
i would check the wiring for cracks
wipers,headlights,speedometer,door locks,air conditioner,electric mirrors, stopped working
Check the fuses; if fuses good, then check the wiring for damage
sound like a bad dimmer switch hi/low beam
make sure your dimmer switch isn't turned all the way down. Then check the fuses next.
Check the fuse.
Usually lights not working are a sign of a bad ground wire in your car if the fuses are ok. Check the ground from the battery to the block. Some people add an extra ground from the trans to the frame to help solve intermittent electrical problems.
If you have power and ground to the pump, the pump is bad.
If a 1999 Jeep Wrangler dash gauge stops working, check the fuse. The fuse may have blown out and will need replaced.
Check you fuses..first
Check your coolant temperature switch first to make sure it is working. Thermostat should be behind the flywheel on the front of the block in the water pump. You have to remove the flywheel to get to it.
