The 2004-2008 F-150 truck was introduced in January 2003 for the 2004 model year as the redesigned eleventh generation of the F-150 lineup.

clicking from behind dash/speedo on idle?

My grandpa’s truck is a 2008 5.4l lariat triton. He is very confused and is unsure what this twitching/clicking noise is. You can only hear it on idle, otherwise engine noise and stuff covers it up. We were thinking maybe a motor was going bad in the gauges, or maybe something else. Thanks for your help!!

Hi,

Don’t know the vehicle or even if this is a help or not but according to this the ford 150 and the Lincoln Mk LT share the same service manual.

Looking at the wiring diagrams , (scroll down to wiring diagrams > system wiring diagrams and click on the link - see p.62 of 127 to find schematic) you could try removing fuse #21 as it seems to provide the power to the instrument cluster - vbatt pin 9. I don’t know what happens to any stored settings etc, radio? if the fuse is removed as I think this may provide the backup power for them as well. Check what it’s called in the fuse panel perhaps.

Also there are a few relays in the cluster so if removing the fuse stops the noise on idle then it may be a relay chattering. The trick may be to find out which one.

Just some ideas.
