Great write up and pics!

cbwayo, He probably fractured the plastic case trying to wedge the motor out. That takes care, some forethought and patience.

The $220 will buy you some time and risk mitigation when you do your own and then resell

cbwayo

Good point. Thanks very much for the help.

Hi, cbwayo, do you have your fan (the green fan without motor) for sale?

cbwayo

I may indeed. I should be receiving the assembly within the week (being shipped from CA) to swap with the existing. Let me find out what the condition is of my fan, as I haven't gotten the chance to take a look at it yet.

Please give a pm if you decide to sell your fan.

Thanks for this great write-up! Just finished the repair myself, it went perfectly

I used an old 911 cylinder to hold the fan while I hammered the motor off

For the UK rennlisters, I just had this problem myself.
I was amazed at the prices some places are charging. The salvage yards would only sell a complete assembly. Best price I got was £195 for a 2nd hand unit.
Looking on other specialist sites for the motor alone, they were all in the range of £130-£140 + shipping.

Decided to look on the Bosch website, where I found a link to local suppliers and managed to get on ordered from an autoparts place in Leamington spa (15 mins from me) at the cost of £70..

Fitted the fan this afternoon. Very easy job, took at most an hour.

If anyone needs more details, pls get in touch

Great write up - well done!

I was about to do the same procedure - but I scored a near-brand-new entire assembly at Hershey for $40!

But I haven't put it in and am in no rush. Despite several very chilly mornings - I've actually found that the natural air flow in the car is MORE than enough to warm me up. The car makes heat in about 3 mintues and with a window cracked open just a tiny sliver - there's huge air flow even with the fans at the "off" setting - assuming you're moving a bit. At highway speeds, the flow is so great I have to turn the heat setting down to about half way!

So those who have had a blower motor failure - don't panic. You can get by in MUCH cooler weather than you think without the blower motor - giving you time to source the Bosch motor and replace it ala this excellent write up.

But with only one front fan motor your windows won't defrost on those cold damp mornings....
Although I found if you tape off the air outlet of the non-working fan motor you can get pretty decent flow from the one working one.

Rally Guy

Might be true - never take this thing out in the damp - so in those cases - yup - this fix is definitely required.

Dragging up an old thread again. Just wanted to let everyone know that I have a blower motor problem in my 993 and used this thread as my guide. It is great even for a 993. I pulled the motor from the shroud and it's the exact same raw Bosch motor (motor only not assembly) as listed on page 1. So any 993 guys that run into this can use this thread and order the same motor and save a few hundred bucks.

Reviving an old thread to update suppliers of the blower motor for anyone looking to do this repair.

I purchased the blower motor from Auto Parts Warehouse for around $128 (after 15% Father's Day discount) with free shipping. The motor came in the Bosch box with the same part number referenced elsewhere in this thread. Great deal since APW often runs pretty good discounts, and other suppliers mentioned in this thread are either OOB or list the motor at a significantly higher price.

The repair was simple and straightforward. In all, it took only about an hour following the very helpful instructions in this thread. This repair sure beats replacing the whole blower housing for $500.

Link to the motor below.

I'm doing this myself. Found this thread via Google. To bad the pics on page one are toasted because of the age of the thread. Bough my motor in Sweden (haven't got it yet). Called Bosch sweden and got names of the retailers their product (0130111145) . Seems it cost $175 here which is ok. Will have it in a week. Hopefully it will go smoothly!

Again reviving an old thread with a tip and a question re: replacing just the motor:

1) Question: removing really tight press fit w/o breaking cage. I'm struggling to remove the motor from the squirrel cage - I've followed all the tips I can find here (made wood block to support cage evenly, center punch, etc. and I've hit it far harder than: a) I would think it would need, and b) than I think the plastic cage could possibly handle (though it hasn't broken). Any tips on how to approach this? I was thinking perhaps heating the cage (slightly) might expand the fit? Heavier hammer?
UPDATE: ignore, I succeeded using a small sledge and a little more persistence. Still amazed the cage did not crack.

2) Tip: for removing motor assembly from housing. Instead of prying motor from housing (as mentioned in this thread) I did the following. First, back off the 2 7mm bolts that hold to motor into the housing but leave a few thread of engagement. Block the housing so that the motor/cage are suspended, then gently tap the bolts with a hammer, alternating sides. This gets you initial separation from the housing and maybe 1/8" of the way out. Then remove the bolts and continue to tap the motor out using a small punch or screwdriver used next to (but not in) the bolt hole threads. (There should be enough space given the gap created in the first step though if your motor is toast, like mine, you don't really care if you hit the threads. For me, very gently tapping was all that was needed and I never felt close to breaking the 20yr old (and expensive to replace) plastic housing.

Hope this helps - thanks in advance for any tips on 1).
