Parker, SD | I mean stupid thoughts come to mind first, intake pipe somehow hooked to the HVAC intake?
Im confused how you can have cab pressure and a sucking sound? Im not sure how raining would effect it at all. Pressurizing could come from loose seals and stuff on like the trans tower and pedals allowing force road air into the cab, but that's a stretch and would be affected by road speed.
Simple though you should have cab vents somewhere to allow pressure equalization, is it a sleeper or day cab? | |
