Did any water get inside your rig that you know of? Specifically behind dash

 

Did you ever figure out this ..mine is doing same thing.

 

Having same issue 2006 freightliner century. All fuses are good none missing. Only air gauges work. Ac compressor not turning on without being bridged. Changed fan clutch, fan clutch solenoid, compressor and ecm and nothing works.

 

Why do you ask;I have same problem, and my windshield leaks

 

BUMPING this Thread because I’m having the same problems, and a lot of people haven’t replied back with their solutions.

2010 Freightliner Cascadia with a Detroit 60 14L engine.
The No oil pressure, No coolant temp, No rpm’s, No A/C seems to work intermittently, at random.
I’ve checked everything from j1939 signals, j1939 resistance, ecm grounds X4, ecm powers X4, a different working ICU and fuses. This may be coincidental but when I push the clutch in when the gauges are working I don’t have to wait(or wiggle the shifter)for the truck to start it fires up quickly, but when the gauges don’t work the truck pauses before starting.



FYI: The air pressure gauges are manual gauges so it has nothing to do with the left side gauges.
