With just the freedom panels off, at around 60mph and the heater on max temperature and blower dialed to 7 (max?), the heat doesn't make it far enough to touch the face of the front seat riders (mode was face-only, and rear vents were also closed). The heat is there and the vents are too hot to touch... the lacking part is pressure.

Is it possible to upgrade the blower fan such as by putting a bigger motor in it or something or by having a second motor and fan (two stage, to turn on when the standard is not enough?)

Thanks for ideas

There are two fan motors. One brings the outside air into the cabin where the cabin air filter resides. The other is underneath the cabin air filter and pulls that air through the filter into the HVAC system where it is processed and distributed (heated/cooled). The recirculation door partially opens at fan speed 4 or higher, regardless of the Recirc button. Unlike a CJ, you do not have full control of the air. If you had a spoiler that spilled (diverted) the outside air over the opened panels then you might win the air pressure battle. The JL design struggles to create higher pressure in the cabin over the outside air with the panels off.

Thanks Dan. Didn't know there was a pusher from the outside. Where is the outside opening to that (cabin air intake)?
