Hello my name is XXXXX XXXXX thank you for your question.
From my experience, this is normally the head lights switch that causes this.
Try this, cause something this will help verify my thoughts
This is easier to see at night
Pull the truck up to a garage door, or a wall or something, if you have someone who can look at the lights that is helpful also.
What I would like you to do is turn the head lights on.
Then after you turn them on
Pull the head light switch back very, very slowly!!!
See if the left high beam comes on at all!
If the light does come on for a second and goes out, that verifies it's a head light switch
That was how I did it back in the day with out going completely nuts checking all sorts of wires.
I did this check first
cause if the light can come on when you pull or press the head light Stalk slowly ( where it may not have made it's full cycle ) It's a internal contact issue in the head light switch
You may find when you have pulled it slowly 1/2 way back or just at the 3/4 of it's movement is when the light may flash or come on
Do you understand?
Yes, I will try what you suggest and get back to you.
You got it!
Let me know how you make out.
I tried what you suggested numerous times and at no time did the high beam come on on the left side. Once in awhile only one of the low beams would workuntil I played with the switch until both were working. Any other suggestions?
If you have issues with the low beam and the steps I gave you allowed them to come on when they normally would not, that tells me there is a issue with the switch for sure
So the head light switch would need to be replaced and operations rechecked.
If you have any more questions on this, please feel free to ask.
If not, and your satisfied with my help, please Rate me. I hope I have provided you Excellent Service.
The switch was replaced about a year ago (new switch) do you think the new switch could have been defective?
Was it a brand new switch or a used switch?
Cause I don't know if even new switches are available any more for that year truck, that is why I am asking.
It was a brand new switch, the mechanics tried a used switch but had not luck so then put in the new switch
Everything your describing sounds like a switch.
Even the fact that you say you turn the light on and have to turn them off and back on to get the light on.
Thank you for the help I will keep working on it

One thing I did not mention was the day time running lights do not work, these are the headlights that are supposed to come on when the vehicle is started.
I played around with the contacts on the switch and got the headlights to work on high and low beam by cleaning them and spraying contact cleaner. Do you think the switch would be causing the problem with the day time running lights?
The DTRL do not work, do you think the problem is in the switch?
