Speedo and display Acting up?

[MRBP]

I have an 07 sd 350 6.0 and the last two mornings when i i started it up the display on the dash with your mileage and direction just goes blank, you can get nothin, then yesterday i jumped in and the display was working but my speedometer was just peged on 120 then it went past that and went back to 80 and so on, now today i jumped in and both where working property and where accurate. Is this a short or is my instrument cluster goin bad i have no idea any info would be great thanks fellas

My display in my 06 F305 was reading that I was either going faster or slower than I really was going. It mainly happend when it was raining or wet outside but sometimes it would do it when it was dry. I talked to a Master Tech at a Ford dealer and he said that it was a common problem and that they recommend changing out the cluster. Also, he said that the connectors in the speed control harness could be allowing moisture in as well. Today I fired up my and there was no speed showing on my speedo and no additional miles being put on the odometer. It could be the cluster finally went out and now will be time for a new one.

If you decide to go with a new cluster you should go with the lariat gauges.

My speedo does the same thing occasionally...I just reset them by holding down the middle and right button (too lazy to walk out and see which is which) and then turn the key on...once the display reads TEST, release the buttons and the guage hands sweep and reset...just a PITA because it always happens when I go into work and I'm doing 60 at a stop light
