Recently when starting the truck, a ticking/knocking noise is coming from the passenger side dash around the glove box. it will last for 25-50 seconds and then stop. When shutting the truck off the ticking/knocking noise from same area will last for sometimes a minute, truck is off. I made a video of the noise thinking I could attach it, no luck. Anybody experience this or have an idea what it could be? Truck runs great, no warning lights come on.
