Check box on driver side firewall under the hood for corrosion. The steer tire likes to throw a lot of crap into it.

Check the grounds down under the starter big bolt 15 / 16  head also if its an RD check the vehicle  ECU plug  under the dash rh side for being greened out as it faces up and if the windshields leak it can cause similar  issues!

Do a google search for “Mack Service Bulletin SB-221-032”. It will outline a complete ground cleaning and check.
