Dash accessories Problem M931

[LtLunatic]

I have dug around in the manuals and on here and have been unable to find the info I need. The problem I am having with my 931 is none of the air powered accessories will work on the dash (they worked fine before). After I run the truck an extended amount of time (an hour or so) they will start working again. and the truck is building up too much air and blowing down. Any help on this issue will be greatly appreciated.

The truck was parked a couple weeks while I was at work. Came home. Fired it up, and here we are now.

Look it up, the TM's are searchable.

Search the site too, for more info.

Did you read the whole thread I linked?

Maybe it is possible to clean it, from this thread.

I think it is shown in post #3 of this thread(pics 2&3).

Hopefully an M939 series truck owner can confirm this is it.

I know Wheelspinner recently replaced his.

edit, A google image search for the number I posted above, matches the item in pics 2&3.

Replace it they go bad. Fleetpride usually has them Napa never has much anymore. I believe it is a part that should be replaced proactively when you first get the truck.
