Dealership, repair shop or alldata.com.

need to know year of vehicle,usually newer than 05 requires dealership aprox 100-150$ repair they have to domanual inputs with "special tool"

unfortunately it is probably the lock actuators on all three, this is a known problem on those, I have worked at a chevy dealer for along time and have seen this many times usually due to water intrusion in the connector at the lock actuator, have been lucky a few times and been able to clean the connectors..

Good job.

Remove the oil sender unit and fit a pressure gauge , start the engine and check pressure, seems odd the oil light and pressure gauge both showed a fault at the same time, perhaps the oil pump relief valve stuck open for a short time.

My guess would be your clock spring has a frayed wire. A common GM issue
Also check your fuses, wiring to horns, and relays. Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/thomas_6b90afb985d8f4bd

Get a computer diagnostics done and it will likely tell you what is wrong. You can buy readers now for less than $100.00. Otherwise you are really guessing.

There is no turn signal relay or flasher , Computer controlled by the BCM - body control module . Turn Signal/Hazard Lamps When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation. The driver door switch and passenger door switch also receive voltage from the BCM turn signal supply voltage circuits for the mirror turn signals. The door switches have no function or control of the mirror turn signals other than a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. The instrument panel cluster (IPC) receives the signals to activate the turn signal indicators over the GMLAN serial data system. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. This is something best left to a qualified repair shop that has a professional type scan tool . Could need new BCM , which would need programming . Scan tool would be able to check switch inputs for BCM .

There are only fuses. The relay is built into the hazard switch. But usually it is the turn signal switch that is bad.

It may need reflashing/reprogramming with the new components . Have you checked for vacuum leaks ?

since you have no noises or ticking at all, you likely have a failed oil pressure sender/sensor. It is located right behind the intake on the driver side on the back of the motor. You are "supposed" to remove the intake to gain access to it (and it is much easier to get to), but you can remove it with a short oil pressure sender socket and a swivel adapter... its close but it comes out.

hook up live gauge to be sure you have press if press good r/r press switch when checking with live gsuge dont run engine long as it can ruin it

Could be that the callipers are jamming or the wheel is running tight. Check for wheel spin with the front wheels off the ground, they should spin with minimum effort. Could also be something wrong with the master cylinder. It may not be releasing properly and slowly building pressure to lock the brakes. After sitting for a while, it returns to normal position and releases the brakes. Mt Ford had a dud wheel bearing which would intermittently start to seize. When this happened, the anti lock braking system thought that the wheel was about to lock and would throw the brakes on and off without warning... Check your wheel bearings too.

Did you try to reset it.

in your oil pan?

My guess is the rubber bumpers for the fuel door are missing causing the door to sit in too far. Probably need like a pocket screwdriver to pop it open. New bumpers are available.
