Light on fornt always on

If the right front signal light of your 2010 GMC Sierra stays on even when the truck is shut off, it could be due to a few possible reasons:
1. Stuck Relay: There might be a malfunctioning relay in the turn signal circuit that is causing the right front signal light to remain illuminated. A stuck relay can keep the circuit closed even when the vehicle is turned off. In this case, you may need to have the relay replaced or repaired.
2. Faulty Wiring: It's possible that there is a wiring issue in the turn signal circuit, causing a constant power supply to the right front signal light. This could be due to a short circuit or a damaged wire. Inspecting the wiring harness and connections for any signs of damage or loose connections would be necessary. If a faulty wire is found, it may need to be repaired or replaced.
3. Malfunctioning Switch: The turn signal switch itself could be defective or stuck in the "on" position. This can cause the right front signal light to remain illuminated regardless of the vehicle's status. Replacing the turn signal switch might be necessary if it is determined to be the cause of the issue.
To pinpoint the exact cause and resolve the problem, it is recommended to have a qualified mechanic or an automotive electrician inspect your GMC Sierra. They will have the expertise and necessary tools to diagnose the issue accurately and carry out the required repairs.

A few years ago I had a pickup with a camper shell. The camper shell light always stayed on even with the switch in the off position. The cause was that the camper light was not grounded to the truck causing the current to backfeed to through the light to ground. Check the ground system in the tail light assembly.

Computer shut off fuel supply after accident. More info is needed, but car needs to be looked at by professional because of SRS system being activated.

if it does not flash it is most likely the bulb may look good but can be bad , take a test light for the socket and see if you test light blinks , if the headlights stay on look in your owners manual should be a light sensor on it so you can set it to shut them off ,

Brake light switch is either bad OR the the stop light switch STOP (in front of switch) has broken and gone. You might have seen plastic pieces on the floor wondering where it came. Get a mirror and look at the switches and in front. If there are open holes in front of the switches and NOT making contact that is why your brake lights are on! Why this is made like this is beyond me, but stupid design.

tail light should be on always; if brake light isn't working look at switches- front or rear m/c. front is most common culprit

What happens when you remove both switches, and wires? What happens when you use a jumper wire acros both wires, on both doors?
