Air leak back there (rear dual air bag / or air leveler / passenger side), don't have short jack so can't get under to work, even test bypass not working, but with air issues, and air control for fan assembly maybe the "why".  Waiting for mechanic, will be long wait on long weekend, need to get bus up.
/sigh...

Phil been a long time since I worked on one but yes if you have an air problem it can affect the fans on those buses!

Thanks Knuckle!!

Found air line going into air distribution manifold came loose (between duals). Re-did the compression fitting, all (mostly) good!   One of the big fans, passenger side, kicked right in. 

But, the driver side fan does not run, any simple fix things to look at ?  I see no override for that fan as I do for passenger side.  Traveling long distances each day so don't have huge amounts of troubleshooting time, engine runs hotter than it should so am going easy. Glad to be heading to cooler climates.
Thank you!

1 fan is for engine cooling the other fan is for turbo inter cooler if the engine cooling fan is working it shouldn't overheat so drive it
