Cold Air From Under the Dash

[Raptorrider2001]

I am feeling cold air blow on my legs on the driver's side. It seems to be coming from just behind the brake release area. Can't find it sitting still and can't reach far enough while moving. Anyone else had this and have a fix? Thanks :confused:

Take off your shoes and socks and you'll have better luck narrowing it down.

There's a grommetted pass-thru down there for routing wires through the firewall. I believe there's a rubber flap that keeps it sealed under normal circumstances.

You may want to verify that the flap is not stuck open.
