2006 EX-l NAVI...206 kmi

Pulled the blower assembly out yesterday because it was making noise. Found a mouse (dead) stuck in the vanes. In addition to the dead mouse residue, the vanes were disgustingly dirty. To clean them, I soaked the fan portion overnight in a bucket (blower side down ofc). Because it is such a bear to remove / install, I hung it from the cabin air filter cross bar to test it.

The operation is sporadic. Turned the ignition on and it jumped to life. Then it stopped. I held it flat like its normal installed position and it came on again. The fan speed buttons didn't provide any control.

How is the blower supposed to operate? Also, how many fans are actually in the car? I can hear another fan change speed when I use the fan adjust buttons.

Thanks.

Yes, sounds like your front blower transistor (if not an LX model Pilot) or resistor module (if LX model) has gone bad and should be replaced.

The Pilot also has a separate rear blower located underneath the center console. You will want to remove the panel next to driver’s right foot and vacuum out the round lint screen.

Here is a link to the OEM part.

If I purchase OEM parts I get them from here since they sell at 30-40% below list and their cross-country shipping prices are very reasonable.

For the blower transistor people have had good luck with aftermarket parts if you want to save some cash.

There's another fan in the center console for the rear vents.

The Resistor is find number 19
79330-S3V-A51 - Genuine Honda Transistor Assy. (hondapartsnow.com)

In case you don't want to pay $115.62 for it, aftermarket parts are available elsewhere for less, about $14.

Every good solution deserves another problem...SMH

Successfully replaced the front blower transistor. However, the blower is not as functional as i thought. It won't start from a stopped condition - if i give the vanes a little nudge, then I can control the speed just fine. But it will be very difficult to bump the vanes once it it installed.

I suspect that I have some binding in the motor linkages. Since I spent more on the transistor than I anticipated (please don't ask), I'd like to see if I can take the assembly apart and inspect the moving parts, Has anyone here successfully done that and re-installed into their car? There appears to be some clip that holds the plastic rotor to the shaft, but m vision sucks and it is kinda rusty so I can't really tell. If I need a new assembly, are their aftermarket ones available?

Appreciate everyone's advice so far...

Pete

Depending on how long the mouse was whirling around in there, it might have been out of balance enough to shake something out of kilter ... or/and jacked a bearing. Feel or hear any roughness or scraping when your rotate it by hand?

It looks like the cage is held on the motor shaft with a speed nut based on this video.

Sometimes you can rock/twist them off with a pair of pliers if that's what it is. I've never personally had one apart but if it won't start on it's own it might be a physical resistance, but it could also be it's not getting full juice. Have you tried connecting it directly to a battery?

Yes, there should be aftermarket motor assemblies. Do a search with the p/n I provided a few threads back.
I helped a friend replace a blower module on a Highlander and I think that cost him $50 for an aftermarket unit.

Not sure what you mean by 'Was it that tab?"...Let's just say that I paid more Honda suggested retail price. :confused:

Update...I was unsuccessful in removing the vanes without damage. However, once the vanes came off, it became pretty obvious that there are no adjustments to be made to the motor. Also, I did a better evaluation of of the motor's operability. While it doesn't make any grinding noises while I spin it, it has A LOT of friction and won't even do a full turn if I give it a good smack.

Bottom line...ordered an aftermarket replacement. Should be here on Wednesday...

Need to depress a metal tab to remove that thermal resistor unit, but then IIRC you have to twist it clockwise, i.e., righty-loosey, while you keep that tab depressed. :(

Don’t feel bad. My local Honda dealer is greedy as well. They charge 30% above list price, so my two better choices are drive 15 miles to the next closest dealer (they charge list price there) or if I can wait a week order from Hondaautomotiveparts.com (30-40% below list price with reasonable shipping rates). Most people likely unknowingly pay above list price at my local dealer because those scumbags note their inflated price as list price on the invoice.

Sorry for the late update...been meaning to close this issue out for a bit. Ordered the aftermarket blower assembly from Rock Auto - just about $50 with shipping. installed and fan control is as good as new.

Ordered it on a Thursday and the shipping options were $9.99 to get it by Wednesday evening or $125.99 to get it by Monday evening. I opted for the Wednesday delivery and it still showed up on Monday. Winning!
