Also looking. I need to do that job next week on my car.

This link appears to work.

Good work finding it. When I click on the pictures to make them bigger I get a "not found" notice. Is there a way to do it or just use a magnifying glass? Thanks

The person who copied the web page included links to the ORIGINAL page for the pictures. Since we can't find the original page anymore, all the links are dead as well. We'll just have to make do with the itty bitty thumbnails.

My motor works OK but only creaks a bit every once in a while. My first thought is to try to lubricate it. I've looked at the photos on this post and am wondering if I could access the motor cavity without all the "removal" stuff, since I wouldn't plan to take the motor out first time around, if the librication did the trick.

I'd appreciate any thoughts from anyone who's been there and done that.

Thanks, srharvey

I completed this job tonight on my 400E.

To answer your earlier question, SRHarvey, it is possible to lubricate the motor without removing the cover, however, you do still have to remove the grills - which are held in place by trim - which are trapped by the wiper assembly - which can't be removed until all the windshield trim is off and the weather stripping removed. Once you can get to the cover it is possible to just see the motor and you could theoretically spray some lubricant in the general direction of the motor and cage shafts. But once you are at this point there are only eight spring clips to remove and have complete access to the motor to change it.

The thread with the thumbnail photos was helpful but for my car it was incomplete. There are additional screws and bolts to remove that are not mentioned in the write up, possibly because my W124 is slightly newer. There are also some T15 Torx screws to deal with, so be sure you have the correct driver.

Also, when replacing the original unit with the Behr motor and fan assembly, some modification needs to be made to the new motor mounts provided. This is to accomodate the wiring harness that passes under and through the mount.

I'll try to answer any questions for people who are considering this job for themselves. If time permits, I'll edit the original post with a couple missing items and photos of the necessary mount modification.

In the meantime, for reference, it took me 2.5 hours to complete the job. It could have been shorter, but I took time to lubricate throttle linkages and wiper linkages, etc. while they were exposed. I also included the time taken for testing of the wipers and all blower settings. Disassembly took the longest - about 1 hour, another .5 hours to install the new assembly including modifying the mount and rerouting some wiring, and another hour to reassemble and test.

Also - very key point: be careful to observe the orientation of the blades on the squirrel cage fans so you can insert the new cages in the correct orientation. Don't assume that if you orient the motor the same as the old one that the fans will also be correct. In my case the new motor was oriented opposite the original and I could have easily installed the fan backwards!

I have perhaps a little above average mechanical skills and a good work area with easy access to a full compliment of tools. Add .5 hours for the average casual mechanic. Tools required are T15 Torx driver, standard blade screwdriver, small phillips screwdriver, 4.5mm hex wrench (allen head), cutting tools to modify the motor mount, 10mm socket and ratchet.

All the instructions worked extremely well for me. When I went back to the postings for checking on prices, I saw information on replacing the brushes (below) so I decided to just lube my bearings which did the trick for me. Just a few hours (a little slow and meticulous work extended my time) and no cash, I've got a great blower.

My 89 300TE was in the shop for 3 weeks and while it sat the blower froze up.

After already paying a hefty fee for a new engine I was not in the mood to shell out $500 for a replacement blower and cages.

I followed the instructions and zened my way through it and found that all it needed (for now) was a helping hand to free it up. Curious that there was no characteristic squeak prior to this freeze up.

Any way I took some new pics and put them here:

This took about 2 hours start to finish.
