my tachometer,engine temp,and transmission temp gauges dont work. on 2004 Ford F-350 Super Duty

What fuses or relays should i check? and where are they located..

Asked by for the 2004 Ford F-350 Super Duty
no fuses and relays. if the other gauges are working, it is most likely in the instrument cluster. a shop with a scan tool can do a sweep test on all the gauges to confirm.

Thank you for that,you saved me allot of wasted time and energy,how much would a test like this cost and are there any user servicable parts that would restore service to the guages in question?
check with a parts store. we send them out to have them overhauled. it is not that expensive.
