Aftermarket blower fan troubles

The original MB blower fan broke down two years ago. Installed a Mahle/Behr then which broke down two weeks ago. Very noisy and almost no power.
Now I tried a Meyle part (I know, I know..., I could not find a Mahle one in Europe and did not want to wait for a part to arrive from the US).
Full power, but a bit noisy in high power. After about an hour it started to get noisy at low power too.

Is it worth a try to lubricate, if so what to use for it? Can you recommend a good aftermarket part for the A1248200608?
 
I went down this road thinking I could save some money, but the fan was so loud in the high position that it was overwhelming. I think this is one of those parts where the factory is the only way to go. After a few days I ordered a factory motor and it was perfect.

If you're going to stay with the aftermarket motor, make sure you haven't over-tightened the screws holding the motor in. There is rubber underneath these screws but if you smash the rubber too much it will transmit the motor noise right into the air box housing.
 
Here is the sad reality, I know there was more than one P/N for the blower motor, but I don't know what was the difference between them.

Edit: P/N 124-820-06-08 and 124-820-13-08 show as NLA, but P/N 000-830-82-08 and 000-830-79-08 show as avalible. What's the difference between them? Because I will be in need for new blower motor myself.

Original fans are NLA, like @emerydc8 said.
This leaves aftermarket parts as the only option, except 30 years old used parts.
Looks like both options are a gamble.

Regarding the rubber dampers: they are not the problem in my case, saddly its the fan itself.

MB made fans in different widths, don't expect other parts numbers to fit.

I've called a few MB dealerships and the original blower motors are NLA. I do not know how good this will be!

Ugh. Was the BEHR (Hella Service) (not Mahle/BEHR I presume) unit made with a Unimotor motor that was made in the Canada…. And a sticker denoting the whole assembly was made in the USA? I remember purchasing one and noting that the motor itself had stickers denoting such. I am wondering if they re-export that assembly to Germany?

Let me check if my Mahle part has the "made in Canada" batch.
I don't think they can be rebuild, but who knows.
For now I ordered a second Meyle part and an used MB with warranty.
The last packages I recieved from the USA took ages and/or got lost. That's why I try to find a faster solution.

Who here is experienced with lubrication of the bearings? What works good for a long time without too much smell in the interior?

I set the motor on end and using a syringe, applied ATF to the upper bearing. Let sit for a couple days, replenishing ATF as needed. Then flip the motor over and do the other bearing. Just be patient and let the ATF migrate into the bearing. I've only done this to one motor and it is working but still isn't as quiet as new.

Thank you, I will give it a try
 

Its saying discontinued now. Slowly but surely most of the parts for our cars are going to be NLA.
I was fortunate to get a BEHR blower motor off eBay (NOS). Once it was delivered and I opened the box, the squirrel cage on one end was broken. The seller partially refunded my money, and I ended up keeping the motor. I will try and figure out how to dismantle the cage from the motor, and probably do a rebuild.
If anyone has done this before, please share your experience.

I've done this several times. First, mark the positions of each cage on the motor shafts and note which cage goes on which side. Then use a heat gun around the area where the cage meets the shaft. Be careful not to melt the spokes of the cage. Just keep the heat gun moving and not in one spot. After a while you should be able to push from the base at the shaft and carefully slide the cage off. Just be patient with the heat gun and let it do the work.

As soon as I get another set of “squirrel” cages, I will try out your method.
 
Well. . .the 1992 Renntech blower motor, aptly named "Squeaky" finally gave up her squeaking last week.
Now, there is no airflow. 30 amp. fuse is fine.

She had been intermittent at best, but now she has, sadly, died.
When I type 000 830 82 08 in the search, I get a LOT of aftermarket blowers.

Any recommendations would be helpful.
 
Use this one. We both have pre facelift cars. One year I tried a VDO brand motor that was a repackaged TYC motor. It worked, but low speed was too fast. I replaced it after a month or two with a BEHR HELLA SERVICE motor, assembled in the USA with a motor made by Unimotor in Canada. That has worked well.

Thanks for the guidance Jlaa! Looks like that one is "For cars with Cabin Air Filter".
Will look one without filter, but am confused as to what brand to try.
