Fuel injected gasoline engines have fuel pump in gas tank. Pump is supposed to "emulsify" (fancy word for "mix") fuel and water to help prevent a localized build up of water at bottom of tank. But ...water and gas don't mix and if you have too much water (caused from condensation ...especially in the winter ...and consistently keeping your fuel at low levels) things don't work so well. Dry Gas ...ancient stuff from carburetor days and frozen fuel lines ....get some, a couple or three bottles at least, and pour into your gas tank then fill up. Dry Gas is essentially (methyl?) alcohol that will break up the water and allow it to better mix with the gas.

Intermittent faults rob years from our lives!!! I've rather a root canal to intermittent fault isolation!! Chapter 11 of Murphy's law reminds us simply checking various spots will cause the fault to disappear until you really need to go somewhere.

Could be a loose or dirty connection so check the fuse box, even if the fuse look good remove clean it and replace. Hopefully you can easily get to the back w/o removing the entire panel. Change the bulb.

Finally is it is a current year model let the dealer do it, should be covered(or not disallowed).

contact the opener manufactures/ distributors and get the operating frequency of the receiver unit . You may need the services of a radio technician to adjust the sender ( remote) to that frequency

walk in to any hardware store and see if 1/2" x 20TP bolt screws in.
if not try all sizes in bin. ask clerk to help, its not hard to do.

if buying nuts, why not ask the sell this. they know.

The flasher looks nothing like the old flashers. It will be located behind the drivers side lower dash (under the steering wheel). It will be a small black box that is about 3 inches wide, 2 inches deep, and 1 inch thick. It may be somewhat difficult to locate because on some of the GM trucks they actually hide it behind the gauges but to the left of the gauges. in the link 1/2 way down shows location and descriptionhttps://www.gm-trucks.com/forums/topic/104429-where-is-the-turnflasher-relay-on-an-03-2500/

signal light control module LM487 ???? How did you come up with this ??? Your vehicles BCM - body control module controls the hazard an turn signals . 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.
Your best bet , take it to a qualified repair shop .
