How Open Freightliner M2 Dash

[@LouSassoleS]

Thank you for your video. I got a air leak i am hunting down and i believe its one of the hoses behind the dash that come through the firewall. Any advice would help if you have done something similar, again thank you.

Of course! The best place to diagnose a slow or quiet air leak is in a quiet place like in an empty warehouse yard. Get the tanks full and turn off the truck. Then listen and wiggle the air lines around one by one. If it gets louder or quieter then you've found the culprit. Also do the same on the engine side of the firewall if you don't find it behind the dash. I hope this helps.
