hello
i have 2010 outlander...just now its giving a new problem.
when the AC turns on or off there is a rubbing sound under the dashboard like some thing moving for switching from ac on to ac off.

have some one heard about this problem?

 

How long does the rubbing last? does it happen at certain fan speeds? when turning or hitting a bump? are you sure it isn't just the clicking noise of the AC condenser engaging/disengaging?

 

rubbing sound last just 2-3 seconds as some mechenical part is moving under the dashboard...its not the condenser for sure ....is there a air valve that opens and closes if a/c is turned off on...its like some parts moves for a swiching action is making a sound which it shoudent...it sounds like humming/rubbing...

 

the blower motor will make a growling noise. it may come and go, but we've experienced it making noise when turning, braking, etc. it was also dependent on fan speed. if you have automatic hvac, I can see how it might growl intermittent. just to rule it out, turn your fan speed on high and see if it does the same.

replacement is easy, if that is the problem.

 

With regards to your post above, my 2008 outlander is making the growling noise you reference especially when turning, braking, etc. Generally it will turn off after a bit when heating is on high, but anything lower than high and it is on. It still pumps heat out but then after a while the heat goes luke warm for a bit. I opened everything up and cannot see anything wrong so I'm wondering if it is the blower motor or not? I don't want to replace the motor if that is not the problem. Any guidance you can provide would be greatly appreciated!!
Thank You!

 

the blower fan is nothing more than a motor with a "squirrel cage" fan on the end of it. The motor is positioned vertically with one bearing below the motor and one bearing above the motor. The lower bearing is nothing more than a cup that a steel shaft sits in. Over time the grease dries up and the shaft grinds on that cup, enlarging the hole. This now allows the shaft to move around, causing the growling noise. To see this issue, you will have had to completely take the motor out of its housing.

I'll also state, there is nothing else in the dash that can make that noise for so long. I will also highly recommend going back to the stealership and buying from them. I purchased a "four seasons" aftermarket unit and it actually whistled when I turned it on. OEM fan works great.

 

Will do. Was going to attempt to do it on my own but have no idea what I'm doing lol. Ready to learn but I think this may be above my grade.
Thanks for the guidance!

 

the blower fan is incredibly easy to replace.
- remove the kickplate just below the lower glovebox. this exposes the motor.
- disconnect an air-cooling hose for the motor and disconnect the wiring connector.
- Remove the three screws holding the motor assembly to the dash...the assembly will drop down
- replace with new parts in reverse order. 45 minutes worth of cautious work...tops.
