I have a repeated issue where the display indicates the AC is on with the fan speed on high yet no air comes out of the vents.  I’ve had the vehicle to the dealer multiple times but they can’t find a problem.  The problem is intermittent.  I had it at the dealer when the fan wasn’t working and they still told me they couldn’t replicate it.   Has anyone else had a similar issue?

Hi Andrew....welcome to the Forums

Sounds like it could be the heater fan speed resistor pack failing.

Should be easy enough to locate it near the heater unit and see if the insulation is breaking up on the resistors in the pack>
Replacement should resolve the issue
