Hi all, recently picked up a M813 from upstate Ohio and Iron butted it home (12hr ride straight through the night). Excited to have the unit. The air system works for the most part however, I am having an issue with the horn and the wipers any suggestions?

welcome @Guzzlebelly and mm well I would say to look up the technical manuals shared on this forum for the 813's, as your wipers are very likely air-operated ones so you're going have a particular air valve relay to look at (it may work again after some banging&cleaning or not..)

The wipers - I would load up an old fashioned pump oil can with some Marvel Mystery Oil (MMO) and after disconnection the air line, give it a short squirt. Chances are that the truck has been sitting for a while and the heat and lack of motion of the Wipers have just made them tired. I would try the MMO several times before you give up and take them apart and clean and rebuild...
