Anyone else have squeaks in A/C blower assembly?

Two days ago I started to hear an intermittent cricket-like chirp coming from behind the glove box when the fan blower was on to #1 or #2 speeds. (Not to be confused with the "behind the glove box buzz" which I fixed up prior.)

I dropped the glove box (I'm becoming rather practiced at this since fixing the buzz ) and took out the cabin air filter and cleaned it (1 leaf, 1 pine needle, something I couldn't identify but looked to be insect-like) but the noise persisted.

It only happens with the blower on #1 (lower speeds) or #2 positions. If I set the blower to #3 or #4 (higher speeds) the noise stops. So I took out the cabin air filter again and watched the blower fan (#87103B on this diagram). On speed #1 or #2 there appears to be a very slight wobble in the blower... higher speeds straightens it out so that it rotates level. I figure this has worn a bearing or is just rubbing somewhere in the assembly as whomping it with my hand moderately on the bottom of the assembly (the part that pokes out from under the passenger-side dash) makes the noise stop momentarily.

I'll likely take it in for the dealer to look at as I'm still under warranty but that's a pain - dealer is an hour away - so it'll be a few weeks before I can spare the time. Anyone had this problem before and know of something I can do (other than keep the blower off or on high ) in the meantime?

 

yes, its very common

 

hmm.. I tried searching before posting, guess I must have used the wrong key words. Hopefully it's common enough that the dealer Service Manager won't look at me like I'm speaking Portuguese and have three heads.

 

post 19 has your fix

clean the filter, check the fan for other debris that got past the filter, then try the known fix:

I'm going to do mine ASAP, it drives me NUTS but I've been cranking the stereo up to avoid fixing it

 

Awesome, thanks! That sounds exactly like what I need.

 

I hear you... I just got the damn buzzing noise fixed and then this crops up. Although it was probably always there but I assumed it was related to the buzzing... now that it's gone I can hear this chirping in all its glory.

 

IMHO the A/C serves no purpose (you don't need to flame me, it's my opinion only), but you should be happy with the Toyota, imagine what the squeaks would end up being on a Ford, a blown-up motor assembly or tranny.

 

Going without AC here is like going without a heater in the great white north.

 

i have crickets too but im starting to get used to them. or sometimes i just turn my music up so loud i cant hear them

 

Sometimes even leaves get down in there... might need to clean it out.

 

this mostly fixed it for me, theres just a few leaves left in there

 

Thanks for posting this! It's been bugging the crap out of me for a couple of weeks. I'll fix it this weekend.

 

mine was blower fan, and had it replaced under extended warrenty. easy to replace.

 

Mine has the squeak too, along with a short somewhere in the fan. It works most of the time, then I hit a bump and it stops. I have to reach down and tap the bottom of it with the end of a maglight to make it come back on. One day I'll get tired of it and fork out the $145 to replace it...

 

I want to do this right now, but it is 19 outside. Maybe tomorrow. Good info anyway.

 

I had the same issue and it turned out to be the blower motor. The dealer replaced it under warranty without a hassle and it has been silent ever since.

 

Mine has done it since I bough the truck new. Once I had the dealer adjust the balance screws, but the crickets came back. Sometimes it does it, sometimes it doesn't, but usually it does and drives me crazy!!! The dealer ordered a new blower motor and getting it replaced on Monday. Hopefully fixes it!

 

This worked for me.

I followed these instructions from post 19

You can see what he is talking about by looking at pics below. However i figured out you really don't have to take the blower out. The black cover will come off the bottom of the blower by taking the four phillips screws out of the bottom. First undo the two clips that hold the wiring in place and then carefully pry the black cover off. You can adjust the two screws on the bottom of the motor from here. It helps if you have a stubby Phillips head as there is not much room. I just played around with it until the sound went away. Re-assemble and enjoy.
This is the blower assembly.

This is a bottom view with the black cover on.

This is the bottom view with cover off. The two gold colored screws are what you adjust.
