I have a 99 Ranger 3.0 temp gauge needle is dead replaced temp switch still dead i can ground the switch and peg the guage out also right headlight isnt working replaced bulb still nothing checked the only 3 grounds i could find nothing checked fuses nothing. Help.

temp gauge: if you changed the sensor and checked the gauge, the only thing else is the wiring between the two. find where the connection is open and fix it.

headlight: have you verified that there's voltage to that headlight socket when you turn your headlights on? check that, and find out where the connection is open and fix it.
