Is everything for the air intake box/tube sealed and secured properly? That's pretty much my wild stab in the dark.

 

sounds like debris caught somewhere to make that sound. Make your dealer find it.

 

Have the same issue with my new 2014 but it gets worse when I come to a stop/idle, almost vanishes at cruise. Sometimes if I fidget with the climate controls, it quits for a while. Kind of irritaing and I'm taking it in. Our friends 2014 we bought together that I carpool with makes no such whistle.
Also, if I crack a window and release cabin pressure, it stops....but the sound is definitely heard through the two center dash vents.

 

Murman had doors' rubber sills leak air. Not sure if related but thought I'd mention it.

 

Yeah, I didn't see anything stuck under the hood or car or intake thinger. Such a pain to take it in... bleh

 

I know exactly what you mean.... I'm doing it at my first oil change. It's a very faint whistle but there. I checked the intake as well, nothing. It's there whether it's recirc or fresh air also. It has to be "something", because the other Pat doesn't do it! I'm hoping it's just a sticker on a duct hose or something. Sounds almost like a directional flapper isn't closing tightly though, due to it coming and going.

 

Mine was doing that one day. I was confused and getting angry. Then I noticed my wife had the vent on her side closed. I opened it up and the whistle vanished. I doubt that you have the same problem, though.

If it is related to engine speed it has to be something in the air intake under the hood. If it is related to cabin air fan speed it is something with the A/C or heater ducts.

 

AndrewTheMandrew try this. When you are up to speed with all your windows

closed and you hear the whistle turn off your blower. If it is what I think it is

the whistle noise will increase in pitch and then suddenly stop as the air flap

closes. If this happens to you the culprit is the actuator that controls the

incoming fresh air flap located just above the cabin filter behind the glove

box.This happens in colder weather when the actuator gets sluggish and

when you set the blower to the slowest speed the actuator just doesn't open

the flap enough and what you are hearing is the air coming through the tiny

slit opening in the flap.What I find works-again @ speed when you are hearing

the noise, toggle the blower off(listen for the flap to close and the noise stop)

and then back on to the first setting listening for the flap to open. If the

noise is gone the flap has opened wide enough at the 1st blower speed and

you are done. If the noise is still there you may have to repeat this process a

few times until the actuator is warm enough to open the flap wide enough for

the 1st setting. Its annoying for sure but it gets the job done. This is mainly a

winter problem as for whatever reason the cold air hits the actuator and

makes it sluggish. Never have the problem in the summer time. Many times

raising the blower speed to 2, 3 or 4 will also eliminate the whistle sound as

the flap is now open wide enough with no chance of whistling.

Good luck!!

 

Could be one of these guys hiding in your vents. Lure him out with some milk and fudge stripe coo-kays!

 

check behind the glove compartment for the following:
1. lid over the cabin filter peoperly closed.
2.cabin filter in place properly.
3.remove cabin filter and get your hand in the blower and see if there is a leaf or anything playing around when blower is on.(happened to me)

 

SpaceJeep! You NAILED IT for me!:notworthy:
I read your post and realized it's worse when it's cold, quiet when it's warm in the afternoon when I drive home.
This morning, (37' when I left the house)....it was whistling. I turned on and off the recirc about a half dozen times (switching from inside to outside air, visa versa) and after that (actuator got warm???), it quit!:smiley_thumbs_up:

Also, as goguadi suggested as well, I'm going to get in behind the glove box this weekend and make sure the filter and lid are properly installed....and make sure the flap and actuator are doing what they're supposed to. Never know...could even be a little piece of plastic molding flash hanging an edge or something.

You guys rock!

 

Hey 2LZ,

I acutally use the blower to accomplish the freeing up of the actuator but hey if using the recirc button works as well bonus!!:smiley_thumbs_up:

Thats what we are here for helping follow Patriot owners.

My 2016 jeep patriot was making the same noise only to find out it was the catalytic converter that was overheating

 

we're here to help eachother.
good luck!

 

found some dead flower under the hood and removed it. But weird that i didn't see it before. It didn't appear to be anywhere near the intakes or vent areas, but the whistling has stopped since then.

I have no idea.

 

Hi gang. Well, I went home last Thursday evening, flopped down the glove box (pinch in the two corner ears. Simple) and there it was, as promised. The little access door for the filter. I poked and prodded. Looked ok but I took it off and checked the filter. It was going the correct direction but I took it out anyway. Looked around with the flashlight, saw nothing out of the ordinary. Reseated the filter and clicked on the trap door, making sure it was seated properly. I didn't want to say anything for a few days just to make sure all was good.
The great news? Since then, no more whistle! Yeah!:banana: Why? I'm clueless. Maybe the trap door wasn't clicked on properly????
Regardless, it's fixed! Woo hoo!:smiley_thumbs_up:
