2004 Pilot, 176k miles - Same symptoms, i.e, going down the road, the front blower stopped, no AC air from front vents, although blower for back still worked. Did the self-check as described in this thread via the post by piealot (Jul 11, 2008) and confirmed air conditioner/heater front blower motor and fan transistor (Honda P/N 79330s3va01) was at fault. Purchased a replacement from ebay store for 69.00 (inc. shipping). While at it, replaced the front cabin air filter (24.00 from local auto parts store) located in vertical slot hold behind glove box. Filter was matted thick w/dirt/dust. Note that if you replace filter, you may have to cut metal crosspiece after removing the glove-box (easily done). For the metal crosspiece, I used aviation shears. Dremmel tool would have worked as well. Too difficult to use hacksaw blade, not enough push/pull space.
The transistor assembly change-out was straightforward. Disconnect plug to transistor assembly, remove three phillips screws, drop out old and insert new one, return screws and reconnect. Heads up, its an on-your-back, under the dashboard, pretzel twisting position you'll find yourself in doing this...however, its a money saver if you elect to do it yourself.

I have a 2004 honda pilot that the front blower quit. I replaced the blower motor resistor and it worked for about 10 minutes and quit again. What could the problem be? Could the new resistor have been bad? Or is something else wrong?

Hi, my a/c seems to working correctly however, at times (usually when stopping) I hear a loud humming/thumping noise. It makes me think there's someone next to me w/a lot of bass! It stops if I turn the a/c off. Want to address it before it gets worse. Any suggestions?

I have an 2004 Pilot and that same thing has happened to me. it does not happen all the time, but comes and goes. When I took it to be serviced and aked them to check it out, they told me everything was normal.

I know that some of the posts here are pretty old, but man did you all help me out. My A/C just quit blowing out of the front vents and after checking all of the fuses that I thought might be the problem I called the shop where I usually get my vehicle serviced, and they told me that it would be six days befor they could even look at it. Well, i got on the internet and found this forum. I followed all of your suggestions and now today Saturday 8/06/2011 the day after my A/C shut down, it is running again! O'Reilly's had me the part and the filter the next morning and it went in pretty easy. I did look on youtube for a video and was able to find this one on how to change the cabin air filter. I helped me to see someone taking the glove box out and removing the metal brace without cutting it off.

Thanks again for all of your help!

#41 of 71 2011 Honda Pilot Passenger AC Control by fny139

Aug 30, 2011 (12:18 pm)

Can this be normal? When the climate control is set to AUTO the AC control on the passenger's side does not work.
 
Specifically, if the passenger lowers the AC to a temp. below the driver's temp. the air comes out colder on the passenger's side but it will just trickle out - the fan will not kick up until the driver's side temp is lowered. Even if the passenger's side is lowered to Low, the coldest it can be set at, the air just barely comes out.
 
The dealer tested the temperature and said it is coming out colder and that this is normal. He said he tested it on two other identical Pilots and they did the same thing.
 
If you are on the driver's side then the fan will kick on right away when you lower the temp.
Any ideas?
 
Thanks you.

#43 of 71 A/C blowing cool air not cold by pjl3

Oct 30, 2011 (7:21 pm)

I have a 2003 Pilot that the A/C is blowing cool air instead of cold, also a noise is coming out from under the dash on the passengers side, has anyone had this problem and what was the problem? Can the problem be corrected by me instead of going to the dealership?

#44 of 71 2003 Pilot Intermittent Blower Failure by remurph

Dec 08, 2011 (9:39 am)

I have a 2003 Pilot with 130K miles on it. The blower motor is failing intermittently.
 
Symptoms/Observations:
- This has been happening off and on for the last 6 months. It has gone weeks or a month without happening at this time, then the issue reappears.
- blower Motor generally fails to come on when vehicle is started, when it fails
- motor appears to not have power at all, when it fails (it's on, or it's off)
- condensor appears to be working, as cool air continues to come out of vents if vent is open and car is moving
- Motor will come back on occasionally, and it coming back on seems to be tied to getting the vehicle up to a certain speed (50-60mph), or RPM (not sure?). Once it comes back on, it stays on.
- Sometimes, shutting the vehicle off, and restarting, will bring power back to the blower. Other times, it will not.
- Interestingly, the radio has lost power several times during this period of time of intermittent loss of power to the blower. NOT at the same time, ever. Shutting the vehicle off and back on seems to bring power back to the radio, although shutting it off and on had to be done several times on one occasion, and didn't work on another occasion (power randomly came back to the radio the next time the vehicle was driven).
- A local mechanic who is a relative of a friend heard about this issue and immediately identified the problem as a faulty NEUTRAL SAFETY SWITCH, but I have been unable to get this person to confirm this, or do the work to fix it. Based on what I've read on neutral safety switches, I see no way that this could be a root cause for the failure of power to the blower motor or radio.
- My mechanic that generally works on the vehicle was unable to recreate the problem, and doesn't have any theories on how to fix it.
 
Does anybody out there have any theories about what could be causing it, and have a strategy for systematically tracking down a way of fixing it?

#45 of 71 blown fuses by jmcc4

Jan 02, 2012 (7:18 am)

My 2004 pilot heat/ac/blower keeps blowing the 7.5 a fuse for the heater control. I'm told the problem is a blower motor but the seat heaters quit too (seat heater fuse is ok). This (these) problem started 2 mos ago. What can I do (other than drive around with a pocket full of extra 7.5 amp fuses)?
