I'm having a (sort of) related issue.

My air just blows warm air. My compressor doesn't kick in at all. Clutch is there, but doesn't engage.

So far, tried the relay and that was not it.

Any other suggestions?

Check your freon level

Would low freon level cause the clutch not to engage/spin?

It makes sense, I suppose. I just was not positive. I plan to get grab the $30 recharge kit today to give it a shot.

[Project_dog]

with out any freon or low freon in the a/c system the pressure switches will not engage. So the clutch on the ac compressor will not engage.

Im on my second a/c compressor. My clutch is failing. Im going to order some parts soon and get it done.

[Tommy]

I had low refrigerant today so I filled it up. Before it got the pressure to the right spot, it made a few weird sounds like it was trying to kick on. Then, it just died. Prior to filling, I got kinda cool air but not enough. Now, its damn warm. Would this be the clutch or the compressor?

[Project_dog]

Is the clutch engaging?

Doesn't sound like it is.

[Project_dog]

Check your fuse. If it's blown. Disconnect you ac compressor clutch. Put the fuse in. If it doesn't blow. Plug your compressor in. If the fuse blows then your ac compressor clutch is shorting out and blowing the fuse.

My 04 2.3 Mazda 3 blew up last night. Coming home big cloud of smoke and terrible rattle squealing noise. I pressed the ac off button and the noise Mostly went away and i made it home. Found this forum last night and took it apart this morning. This is what i found. Is there more bad here then just the bearing?

Is the clutch still gonna work or is it as trashed as it looks. Also this bering is totaly trashed and will not come out with a hammer. Whats the trick?

[HawkeyeGeoff]

God the AC in this car blows....

Have a machine shop press it out and in. I just did mine it works beautifully. On a side note be very careful with the pulley it isn't that strong. DO NOT HAMMER it on or off you will have a bent pulley, and the ac clutch pulley is expensive.

Step 1, I jacked up the car, removed the passenger side front wheel and removed the inner fender liner to reveal the A/C clutch. Step 2, I proceeded to remove the 10mm Bolt holding the A/C clutch on, at the same time you must use a flat head screw driver as a wedge to keep the pulley from spinning as you remove the bolt. ( Much easier than it sounds) Step 3, Now you should be able to remove the clutch by just pulling, I used a flat head screw driver to pry it off. Be care full not to loose the 2 shims on the back side of the clutch they are very important. Step 4, Now you will be able to remove the C-clip holding the pulley on, and pull the pulley off. I had to use a gear puller to pull mine off due to the fact that the bearing in the clutch pulley was so warped i couldn't pull it out by hand. Step 5, This was the hard part.. Autozone List a bearing for our A/C compressor clutch online as MT2233.. THIS IS THE WRONG BEARING!!!! So I Take The broken Bearing to a local Bearing Shop and try to buy the exact bearing... The Bearing is a NSK 35BD219DUM1 The bearing shop said they could order me the bearing but it would cost 70 bucks... screw that so i measured the dimensions of the bearing the bearing measures out to be 35x55x20 So I did some more research and found that auto zone carries a bearing in this size But does not list it for our car. THE CORRECT BEARING IS MADE BY SANTECH AND ITS PART NUMBER IS MT2021!! Total cost of the bearing was 23 bucks.. Step 6, i took bearing home and it was already late so i threw the new bearing in the freezer and let it freeze over night. so that it would shrink a bit and be easier to press into the pulley. Step 7, set pulley on a wood block and use a rubber mallet to gently tap the bearing into place. MAKE SURE TO PRESS BEARING FULLY INTO ITS SEAT ON THE BACK SIDE OF THE PULLEY. From here, re install in the reverse order and be happy I will attach pictures of the steps along with a video of how the car sounded with the faulty bearing I hope this is useful and saves a lot of you guys a good chunk of change.

hi

I just saw this post over the internet after I realize that my ac is not running anymore.

if its seized , Can I change only the bearing to fix the problem.? the wheel with the 3 spoke is not turning when the ac button is on )

thank you

[btstarcher]

It's not seized. Nice first post brownie. Search.

Your A/C compressor clutch isn't engaging. If it were seized the belt would shred itself or (most likely) the engine wouldn't even start.

Hi

Can't find replacement compressor. Well, O'Reilly has it but for over $700.
It comes as Murray 97470 part, but Autozone told us it's out of stock. For period unknown.
Autozone was going to sell it for $407.
I can't find same ac comp online.
Help is very appreciated. Car is non-drivable as of now.
Thank you

[Project_dog]

The dealer ship in spokane wa is like 380

This is the only reputable place I'd ever go:
2009—Mazda—3—A/C Compressor from DiscountAcParts

I went OEM and haven't looked back. Yes, the Panasonic unit sucks. But compared to every aftermarket option, it's infinitely better.


EDIT: If you have a 2007 make sure you get the right compressor/belt. There were two different sizes made, depending on the month produced.

[eleitner8914]

My commpressor was rattling so I took it apart and the bearing was fried. Replaced the bearing as noted in the first post but now the compressor will not disengage an suggestions ? AC blows ice cold but there is a lot of ice build up due to is not disengaging. Any suggestions on what to check now ?

[craigbruinsfan]

Does anyone know where I can get this bearing in Ontario, Canada? I tried calling Canadian Bearing who said that they cant get the part anymore and that its proprietary and only available at the dealer. What sucks about that is that the dealer only sells it as the whole assembly now which costs 270 bux. Any help would be greatly appreciated!

[BlaZenem]

think i need to do this as well

[BlaZenem]

does anyone know if this applies to a 2006 mazdaspeed 6? same bearing MT2021? its 21 bucks so im gonna go get it and try...

AC Clutch Bearing 35BD219DUK 35x55x20 Honda Infiniti Dodge GM Acura | eBay 12.25$ shipped

i found my clutch plate to be kind of wobbly will this address that? the rubber in the 3 holes is coming out of place

[Tommy]

Turns out I just needed a new charge. First charge didn't take somehow, vented it empty and used the heavy duty stuff. The ac was on and off for a day and has worked perfectly in the last week.

[Nitr0EngiE]

I posted a issue previously about never being able to charge the Ac correctly the car simply would not take the freon from the cans it took a tiny bit then no more.

I found the trick is you are supposed to charge about 8 ounces into the HIGH side with the car OFF first and then put the rest in low side with the car on

WARNING if you try to charge the high side with the AC and car running the can will blow up and you will have a shitty couple of weeks recovering.

i did this and now my ac blows cold and good and i did not have to pay Mazda either like the last 2-3 times i had to have a shop do it because it would never take the freon. When i asked about it on the fourms noone could tell me why the car would not take the freon then a youtube video exposed to me that the service manual directs you to charge high side first.

[Tommy]

You fucked up then. I did it with car and ac on. Just a little at a time.

[Nitr0EngiE]

i didin't fuck shit up there is a procedure for doing it in high side first and if you dont it causes a head ache. if anyone wants to get it done right follow what i said about charging high side first its in the service manual if you dont believe me.

[mrmonk7663]

If you have the time and patience, try to post the video you are referencing. Thanks!

I had similar issues with compressor kicking on until charged the High side like I have been saying this whole time. we could not get it to take freon

[jdub289f]

Trying to do the same thing on my 2004 3s. I think its completely seized and screwed! Can't get the bearing out when I'm beating on it hard. I think it got so hot to the point where the whole thing seized...oh well

[bjc]

Hi all,
Posting from Australia with regards to my wife's 2010 Mazda SP23 (2.3lt!) and aircon troubles. The unit itself starts fine and runs good with no noise until it switches off (or turned off) and at that point it makes a rattling noise while winding down? I originally thought the clutch but it engages and disengages fine and condition looks ok overall, plus the fact there is zero noise until it is winding down! I would assume the pump itself has had it and before looking at schematics I thought it would be a simple design, wrong...

Anyway...has anyone else had similar problems of failure or this noise?

Cheers,
Brett

[albone]

I have a 2008 MS3 and MT2021 is the correct part no from autozone. Thx for the post!

[Nel Mazdaspeed]

This thread is coming in handy to me and since I didn't notice a diagram of the dis-assembly of the a/c clutch unit I thought I would contribute.
*****This is for the 2009 MS3 105mm clutch unit.*****

[bjc]

Just an update on my problem from the above post.
The wife couldn't wait any longer and summer is nearing here so she went ahead and had it fixed. The compressor was the only problem so had to be replaced which the cheapest we could find in our town was $1400aus! Very expensive considering the price of a compressor is less than a third of that but you can't win them all I guess...

[Nel Mazdaspeed]

Mine was doing that. . Once I took the bearing out of the pulley I verified tjat indeed was the problem.. cost me $21.99US..
Unfortunate you had to take it to a shop though but atleast it will be fixed

Hey im not sure if my problem is the same or different but the problem with my a/c compressor is the clutch does not engage when the a/c button is switched on. What is the fix for this?

[jasperwill]

Hi Everyone! Im pretty sure my 2012 Mazda 3 has this same issue. i have the non-skyactive 2.0 liter model. does anyone know if my little base model mazda has the same compressor as your bad-ass mazdaspeed versions?

Nope. Different part#, so different compressor...
