The only relay that could be an issue would be if you still have the control relay as was on early systems. That would provide power to all the buttons & was turned on via the ballast resistor ign wire from ign switch. Shortly after production started relay was eliminated and the power to buttons came directly from the ign switch via the resistor feed wire.

You said you had reverse lights, so that relay or the feed should not be the cause since those would be out as well. Any other relay sticking would cause some other symptoms you would see or hear. Pressure switch for the P. N, R button not being closed and you also wouldn't have the reverse lights or be able to crank the starter motor.

I don't think you can totally breathe easy yet. If it happens again need to verify exactly what does/doesn't work. One possibility if it's only the H, L, D buttons is the common feed to those. That square plug under dash could stand a check to make sure none of the contacts are halfway out of the housing & making a poor connection.
