Pull the gauge cluster from the dash...takes about 10 minutes once you find the right bit for your screwdriver. There is a single plugin in the back of the cluster remove it and clean with contact cleaner, clean the plugin and the contact in the back of the cluster. Apply some dielectric grease after cleaning then install the cluster back in the dash...this may fix your problem for hours, days, or weeks or more...i did this to my CV713 for a year about once a month...then ended up buying a new cluster...problem solved. So if the cleaning works for you, set back enough money for a cluster as the truck keeps working.

Sounds like you need a new cluster. The pins break off of the circuit board. Had the same problem with my '03cv713, tried everything with the plug, new cluster fixed it. Was about $600.

Just out of curiosity here, the service bulletin for the 02 and earlier (03 maybe?) wont apply here? I ask because my truck at work is an 05 vision (sorry don't know my mack model numbers yet) and suffers from gauge drop out constantly, as does the 03 vision, and its not the first mack I have driven that has suffered from gauge drop out, a few granites did the same thing. Its getting irritating at this point.
