Hey all, I have a 2019 Expedition Limited and I have had some issues with the HVAC smelling musty right after when the truck had AC on. I've tried the disinfectant method on to the HVAC intake through the cowl but it comes back eventually.
Upon further review, it looks like F-150s and super duties also have the same issue to due to poor design on the AC Drain through the firewall. The fix is a rubber elbow (looks like a PCV valve elbow) as seen in this video
I have ordered the "Ford part" as noted through Amazon for $18 and I am currently waiting for it to try out if this is the right fix. I am just curious if others out there in the Expy/Navigator world have had the same issues.
