Just picked up our 2016 Entegra Anthem, dash a/c working fine, we were 15 miles from the dealership and when I turned on the dash a/c fan switch nothing happened. Could hear the a/c compressor kick on but no air coming from the dash vents. All fuses are ok, any ideas on what could have happened? The dealer said we could bring it back but I thought it must be something minor since it worked fine a few minutes before. Help!

Do you mean no air or no cold air? Confirm the ac compressor is actually running at the engine when in ac mode.
The pulle runs all time with engine but check that the clutch is engaged. If the compressor is not running you possibly have a leak as there is low pressure cut off switch that will not let the compressor engage when the pressure is low.

I'm trying to say: No air is coming out of the vents. Also it appears the compressor is running and the clutch (on the air conditioner) has been engaged. I'm thinking it may be a defective fan speed switch. The knob rotates but there is "NO CHANGE" in the air volume coming out of the vent openings. Thanks for your opinion.

I just received a Spartan Technical Service Bulletin from Spartan describing that problem. TSB 18-006 for the A/C control switch. Sorry The TSB is at the MH or I would post it. I do not know what dates are involved, but a call to Spartan can answer that. Maybe someone else that has received the TSB can add to this post with the dates involved.

I tried searching it without any luck.

Fuse should be in comp forward of driver side front tire. I'd pull AC control panel and check for loose or disconnected wires. Check for loose grounds behind dash as well.

Here is schematic, it shows typical blower motor wiring https://drive.google.com/file/d/0Bzy...w?usp=drivesdk

Here is troubleshooting guide that gives all the reasons the blower may not be working and remedy, see problem #3 https://drive.google.com/file/d/0Bzy...w?usp=drivesdk
