Blower Motor Removal

I have been hearing a vibrating sound from my blower motor on recirculate. Now I get it on any setting. I suspect that something got into the ducts.(sounds kind of like paper)

How is the blower mounted? I disconnected the power to the blower, but I can't see how to remove it. Also, where are the air intakes for fresh air and recirculated air?

The blower motor is located on the passenger side of the vehicle under the dash. The blower motor can be removed from the vehicle without having to remove the HVAC housing.



1. Disconnect and isolate the battery negative cable.
2. Unplug the blower motor wire harness connector .
3. Release blower motor retainer-locking tab and rotate blower motor counterclockwise.
4. Remove blower motor from the HVAC housing.

INSTALLATION

NOTE: Failure to install the blower motor assembly correctly could result in an air leak or the blower motor assembly becoming completely disengaged from the HVAC housing.

1. Align and install the blower motor into the HVAC housing.
2. Rotate the blower motor until all of the locking tabs have secured the blower motor assembly to the HVAC housing.
3. Connect the wire harness connector to the blower motor.
4. Reconnect the battery negative cable.
5. Test the blower motor for proper installation by turning the blower motor speed to its fastest position and checking around the outer edges of the blower assembly for air leaks. If any air leaks are found, remove and reinstall the blower motor.

The motor was mounted 90 degrees off. I found a soda straw wrapper in the motor. Everything worked great and it only took a couple of minutes. I installed it like the picture showed. Thanks again.

90 degrees?! Is your jeep secondhand? Do you think that was a factory mistake or what? That is just odd.

I am wondering because mine has been making an odd noise too. I just haven't made time to fix it.

Old post, but I can't figure out the retaining tab that locks the fan in place. Anyone have a pic? The only thing I saw was two little tabs. I pushed them up and I still can't turn it.

Okay I got. Here are some additional pics that should come in real handy for the next guy. I hate messing with this stuff. Of all the DIY Jeep projects, I have been the most frustrated with this and the blower motor resistor. All said and done the noise is still there and I broke the retaining tab off.

There are not the tab. These should be left alone.


Close up of one.


Here is the broken tab base. It is in the back of the motor. Get a mirror or feel around carefully.


Here is the other part.


Here is the motor and blower removed.

I am getting ready to remove mine in the morning as I have ther loud sound on high recirculate. What do you do if you break off the tab?

You can buy a whole new one or stick it back in with the broken tab. I stuck mine back in and added a little duct tape to keep it from potentially vibrating out. It's been like that for going on two years.

My roaring noise was the result of part of a straw paper cover and some pine needles. Thanks for all the info. I was able to get out the blower motor without breaking the tab and got it back in place. The mirror was a great suggestion. Here is a picture of the debris inside the fan.

This is WRONG.

Step 1 should be like this:

I too was having the same rattle problem in my 2005 TJ. The tab is at the front right (firewall) side and can easily be found by reaching your hand up and running your fingers along the rim until you find it, no tools are needed and you don't need to turn yourself upside down to get at it. All it needs is a gentle tug downward to release the fan. Don't pull it more than a 1/4" or so or it will break, it only needs a little pull to release it from its locking slot, then twist the fan towards the drivers side seat. The wire plug is released by pulling the little red locking tab out and then squeezing the connector. The fan was filled with pine needles and twigs that get through the hood screen intact. I cleaned the cage with soapy water and a brush, blew it out with air and simply snapped it back in place with a twist towards the passenger door, about a 5 minute job to stop months of annoying fan noise!
