Bad charging system? alternator or generator does not supply enough power to keep battery charged to operate accesories.
Bad battery? can't hold charge.
what about the day running lights? You want to know how to turn them off?If you do then once you start the truck turn the light switch to the left and that shuts them off.
Daytime running light module may be the problem
I am not a mechanic, however as an electrician it sounds like the running board lights are wired to the same relay as the interior lights. To check this, simply crank the truck, leave all the exterior lights off, turn on the interior light, then walk around the truck and look at the running board lights. If they are on then turn the interior light off and the parking lights on, check to see if the running board lights come back on. Depending on the make and model of the truck, I could be way off in left field and this info may not apply. uuummmm.....programing?
If you mean the daytime running lights , just put your emergency / parking brake on when you are parked
Unplug daytime running light module. It is located on driver side just under the front of the truck.
have the alternator tested or replaced

Back track on your connects and ground wires. I bet that does the trick. If not test your sockets and fuses. fasttony46@yahoo.com
daytime running lights for chevys are automatic. you cant turn them off. all you can do is control the high and low beams.
If you cut the wire from the light switch to the frount running lights (single use light) you can then hook a new wire from a keyed power source (check manuel) and the running lights will come on every time you start the truck. costs $Priceless
Take a light tester and check the pins at the truck side trailer plug. With the truck set for running lights check for power at the pins. If there is power then there is a loose or bad wire on the trailer side. If there is no power then there is a power problem on the truck side.
I have a 1990 Chevy 1500 truck the brakelight switch is disconnected and it has no connector going to it. I replaced all the bulbs. And still my running lights are in the on position when i turn off the truck. My brake lights are still not working after replacing the lights. I have a RV brake accuator also under the steering column can you help me solve my problem?
