It sounds like the switch is out but it might be the dimmer switch as well. Here is a guide and some headlight wiring diagrams so you can do some easy testing to figure out which is bad and needs to be replaced.

funny thing. Yesterday the lights worked properly, today the switch doesnt activate the high beam indicator lamp. Bad switch or bad connection?

Get a test light. Find the hi-low beam selector switch on top of column under dash, test light green wire for power when in hi-beam mode, if no power then the switch is probably bad

the low beams on my truck work fine but the high beams dont. The high beam indicator lights up when I activate the switch. Could it be one of the bulbs is burned out or is there a specific fuse?

Test for power at the headlights with hi-beams on, if none, then it is the switch otherwise the hi-beams may need to be replaced

When you turn the switch, head lights will not come on, No High or low beam. The parking lights work. When you hit the passenger side blinker, you get a fast flashing turn signal. I checked all the bulb's and they are working. I checked the fuses and they all look good. Any suggestions will be greatly appreciated.

Sounds like a possible bad head light switch. Are you 100% sure all the bulbs are ok. Did you check the side marker lights also.

Check main fuses under hood. Check wires for power and trace to locate open circuit.

low beams quit working, tested the headlights to see if they were good, they were, checked fuses, replaced the multi-function switch, the low beams came on then all of a sudden they quit working, checked everything out again but they still won't work? Any help would be appreciated,

Actually the truck is a 1500 pickup, we checked the DRL relay and the switch is between 3 & 4 which according to the diagram on the switch is correct. Thank you. Shirley

thanks

Check the daytime running lamp (DRL) relay, let me know how it tests.

OK, perform following test steps..

Head lights are protected by a thermal auto-resetting circuit breaker inside the head light switch.

That 12 volts you found at the head light switch should be on the red wire. Next, you should have it on the yellow wire when the switch is in the head light position. If you have it there, we'll have to move on to the dimmer switch.

Check the head light switch and the connector for blackened terminals or signs of overheating and melting.

The tachometer and speedometer will quit working while driving and the pu does not have full power. We have to stop, shut the pu off of a minute, then restart. It usually fixes the problem. Also, when driving at night with high beam headlights the lights will go off. Eventually they will come back on.
