I'd say a "clanking" or "rattling" sound. Not a grinding or squealing type of sound. I changed out the condensor several months ago, and like I said the air blows really cold regardless.
A noisy problem recently reared it's ugly head. When my '07 LX is not warm (1st startup of the day), it goes into high idle mode (1500 rpm) for about 15 seconds then starts slowing down normally. However, if the AC is engaged, a noisy racket is present. I can shut off AC and it immediately...
I came across this thread. Sorry for the stupid questions but I'm an electrical moron. In reading this guy's remedy, isn't his solution based on a working small horn wire giving power to the new relay? My problem seems to be no power getting to the horn in the first place. Thanks again.
Thanks again. It does appear you have to replace the entire junction box/fuse assembly instead of changing out one measly relay switch. What a load of crap....

I also found this online that seems to...
So I hooked up my multi meter to the horn, positive to the power slot in harness, negative to horn bracket (ground). When "honking" the horn via steering wheel engagement, I can hear clicking in the fuse box supposedly where the horn relay is. I get nothing over the multi meter when doing...
I've already done that, and the horn relay is not in this particular fuse box according to the map you are referencing. There are other relays in there though, just not the horn relay. I am assuming there are other relays underneath there somewhere since the diagrams I have seen...
Thanks and I stumbled into that as well. My fuse box has some small clips all the way around it on the outside of the box. Looks like you could possibly separate the fuse box in half? I'm wondering if those relays are underneath the fuses?
To answer your question, those relays are not...
I took the horns back off, and checked them with 12v battery. They both work that way. I then checked power to fuse and it checks out good. Seems to be issue between fuse box and horn hookups? Not sure how to check the 1 wire pin at horn to see if power is getting there.
The low volume horn quit working about a month ago, and the high pitched horn was working fine. I took them off and swapped them, just to see if it was an actual horn problem, or something else. It didn't work, so I put them back where they belong, now neither of the work. All I knew to do...
I got lucky with my MAF. Bought some cleaner at AutoZone, sprayed her down, waited about 30 minutes, and it actually worked. Really smoothed out that rough idle at 600-800 rpm.
Thank you so much for the most informative post. I'll try some of those tricks on the purge valves. Just to be clear, I can purge the fronts and the accuator, just not the rears. I want to save the AHC, as the ride is butter smooth. I like it alot.
