<![CDATA[e39 blower motor issue]]>Driving like normal and randomly the blower quit. Checked glove box fuses fuse 28 was blown replaced it and nothing changed. All other fuses looked okay. Any suggestion on whay to check next. I had my battery disconnected today for like 10 minutes if that may have anything to do with

Turnes out the fuse i replaced (28) was bad and i didnt notice it?  When i originaly replaced fuse 28(was blown) it didnt work at all still. Replaced with a 10a(calls for a 30a but thats all i had on hand) started up and worked great. Not to my surprise that fuse blew right away i will be buying a new 30a and enjoying my heat another day

That's not been my experience before but the fsu is the simplest part to replace if you want to start throwing parts at it.

Well i have been under looking for fuses 75 and 76 i can onky find one fuse under the glove box area i removed what i could and all i see is one larger 50a fuse that does not look to be blown i belive i am hearing a little noise in the area while my head was down there i was hearing an almost thunping noise and the car has been off almost all day. When i turn the fan on it does not work but i hear an ever so slight noise. Any suggestions on finding that other fuse or the noise i am hea

Not to thread jack, but owned close to 110 cars? That sounds like an obscure amount...

If it were the fsu then you would have blower action in the highest setting.  You probably lost your blower motor.  Was it making any noise before it failed?  ticking, squealing, etc?  I would check EVERY fuse with a test light before I replaced the blower motor.  There could be another circuit controlling the blower action that you have overlooked.

Iv been reading forums sll day and the fsu can fail and cause no blower action at all settings

Honestly there was little to no noise to indicate the blower was bad. I said abive there might have been some noise but the more i thinkof it any noise i heard was onsidered normal to me as iv owned roughly 110 cars.  But who knows going to have to get down and look

I found a used one otherwise someone mentioned in a forum about a using a certain Mercedes blower that was almost the same dimensions but much cheaper for some reason. I replaced it from under the hood by removing the plastic cover. It was not easy but seemed better than removing the whole hvac box inside the car.

Check all fuses with a test light as this will eliminate all options.  If you have a voltmeter you can check and see if power is getting to the BM at the plug.
