The cab air filter is in the hvac panel. Here is a picture of how to remove the cover, the filter is a blue colored mat on the right side of the evaporator and heater cores.HVAC Cover.pdf Quote "Mebbe I'm too ugly and stupid to give up!"

I kept the bone yard panel in it and haven't had a problem since.http://www.bigmacktrucks.com/index.php?showtopic=14797&st=0&p=59443&hl=+seat%20+belt&fromsearch=1entry59443 Quote Link to comment https://www.bigmacktrucks.com/topic/15112-seatbelt-light/#findComment-60873 Share on other sites More sharing options...
