at time i have a ring noise come for the blower. only on lev 4 (ex high)

 

Yes Mine makes the noise

 

Mine also. Friggin annoying.

 

Yea mine too I took apart the glove box to investigate and found nothing!

 

Here also, even at low speed

 

Mine did in on low and the colder it got the worse it was. Of course the 2 times I brought it in it had warmed up and decreased. The last ime I had it in, they had it overnight for the fuel fill problem (wrong filler neck, not fixed yet). They keep the cars in and I had to give them permission to leave it out to check in the AM when it's coldest. I received a new fam motor. Quiet again.

 

I was going to say it's a fan motor going out. I had one once that siezed after it made a ring sound on the medium speed for 6 months.

 

I get it, but only on the defroster/floor setting when high.

 

mine was at high and when it was set for the floor. its a door on the vent not closing all the way. they pulled the dash out and replaced it. thats when the trouble started. i picked up went home and went back out to go to the store. jeep wouldnt start. so i used the key i let them have and it started. so i head to the dealer to get key programmed and everydamn light on the dash came on. dealer said no codes came up.i tried both keys and went back home guess what, i shut it off and tried later to start the jeep no start dealer found 15 codes turns out sumone didnt plug a connector back in all the way, which they found after they pulled the dash again
