additionally when i turn the key to the on position (not starting the truck) the buzzer activates and continues to buzz until the truck is either started or the key is turned back to the off position. to my understanding, the buzzer should turn off after a few seconds. Could this have something to do with my previous question?

Maybe the switch for the low-air? -- Not familiar with that model truck.
