Thank you. I couldn't tell from online searches whether those were actual working vents. I will look there because that would be a logical place. Thanks again.
Unusual request. Something has crawled into my JT and died. Probably a mouse. Strongest smell coming from the read of cab. Any ideas of potential entrance points or final resting places? We've searched (including cabin filter, etc.) but haven't found yet. Smell dissipates when truck is moving...
