Fan Blower Fuse for 2014 AC System?

On my wife's 2014 Jeep, the fan quit blowing air and doesn't come on at all.

I've looked under the lid of the fuse box and don't see anything appropriate to what I'm looking for.

I see some labels for HVAC and auto temp control, as well as some for the radiator fan, but nothing else lbeled for fan or blower.

Does anyone know which FUSE is assigned to the fan?

AC and heat work fine as in it gets hot or cold but there is no moving air, and there are no other CEL or codes.

See pp. 617-623 of the Owner's Manual. Which fan are you referring to? The blower motor or the radiator fan?

Front blower motor - cavity J15, 40 amp, green-colored fuse (p. 618)
Radiator fan - cavity J12, 30 amp, pink-colored fuse (p. 618)

Lol, thanks... of all places we didn't look... must be a guy thing.

Yes, the blower, J-15 looks like it might be the one to check.
If that doesn't pan out then we'll pull the panels and check the wiring connectors on the back of the switches.

its a 14, why are you jacking with it at all? Take it to the dealer.

I mean, I am all for doing my own work, but this seems like a case for the dealer to fix for free. And I could see the dealer denying coverage if you take it in and they see that you have been messing with wiring connectors and covers and switches and yada yada yada.

+1

A fuse in theory should never blow under normal conditions. It is telling you something is pulling too much amperage. Could be a chaff condition with a short to ground or the blower motor is bad. Either way, the dealer should be dealing with it while under warranty.

Yeah... but you never know which of my kids has been doing what to where with whatever... I at least want to check the fuses.

Ok, for the record, the inside of the fuse box lid with the fuse box layout labeled fuse J15 as Front HVAC while the book reference listed it as J15 Front Blower.
I didn't have access to the book when I was initially looking for the fuse, so you can see where my confusion started.

...and, the dealer sez he will need to keep it for 2 days... just to change a fuse?

Ok, the fuse is fine...

Interesting that you are having this problem. My rear defroster light blinks for about thirty seconds, and the fan or AC will not come on during that time. I took my Jeep to the dealer yesterday and he sent a message to the tech group in Texas to try and see if they knew anything before they take it into the shop.
