When running the air conditioner or heater the fan is making a terrible noise and it is getting worse. Sounds like its about to quit working.
Fan does not working with 3 first level, only 4th level is working but then my AC turns off:(
Running heater or AC would erratically produce a horrible loud noise from the glove compartment area. I removed the glove compartment and surrounding containment parts and found the blower and filter assembly. I removed the blower motor (easy) and the fan from the motor and found a fine layer of black dust. My first thought was bad bearings (BTW I know nothing about cars). I sprayed some WD-40 in the moving parts of the motor and replaced the fan. I reinstalled the blower motor and we had not noise for 2-3 months. Now making noise again so I'm shopping for a blower motor for a 2007 Mitsubishi Outlander but all websites showing pictures show a different blower motor than the one I'm replacing. I can't find the one that was in my care anywhere, nor can I find any info advising of a change or model number. The model number from the sticker on the motor is CSA431D214A and Made in Japan by Mitsubishi Heavy Industries, LTD. A Google search for that model number only returns a few hits and they are all European. My car was manufactured in March of 2007 and the blower motor shows a manufacture date of February 2007. I don't want to pay a dealer for such an easy part to replace but I'm not sure how to find the right motor. The search continues.
squealing and groaning fan blower...AC is cold...but blower finally stopped working
90 degrees and the fan just stopped working - thing it might be the 30 amp fuse I replaced it but it still isn't working - I can feel faint cool air but no fan
This was a recall. Take it to your dealer...don't get ripped off by local auto shops.
noisy blower motor
Blower Motor failed. Any Cold or Hot air when you turn the switch.
fan noise is awful!
blower motor went out and was replaced. Three years later and its out again...
When using air or heat loud noise when blower comes on
aircon is down .. i think its because there is no fan blowing cold air out ..
replaced motor assmby
Heater, defroster makes a terrible noise when running
erratic operation of fan blower
Erratic a/c. Sometimes it works fine, some days it only blows according to the speed of the car with no cooling. Has to be off when car starts to even have a chance of it working.
it is winter & i have no heat now!!
