Tach doesnt start at zero
I have an 07 xlt and just this weekend while on a road trip i noticed my Tach was at almost 4000rpms when cruising at 65mph. I started to freak a bit thinking the trans wasnt shifting correctly or something. I was able to get my SGII to show rpms and of course it displays correctly. and then to top things off my speedo back light is out so i am unable to read my speedo at night. Does this mean I have a faulty cluster and will need to send it into the circuit board medics?
thanks for your time

I had my tac go wacky once and there was a reset procedure for it but I don't remember what it was. One of those turn the key while hopping on one leg while balancing a beer on your nose type of things and it got you into a programming mode. I'm sure somebody on here has that procedure? Not sure if that will fix it though. I had to have my cluster repaired because it intermittently lost power sometime after that procedure fixed that issue.

Does the numbers seem to read right when it's running or are they odd also?
For cluster issues I would go with
