Blower motor not working

You mentioned that you checked the fuses in the fuse box. But there is also a " fuse link safety fuse " located on top of the driver side front shock strut ( under the hood. ). Mine has failed twice. They cost perhaps a dollar or two. And it takes sixty seconds to change out. It is located on my car in a black plastic rectangular shaped box about the size of a large key. Just pop it open with a flat screw driver and ( after disconnecting the battery ) just unscrew it and clean it. Pay particular attention to where the washers go. It is a hassle to disconnect the battery which I do not do when changing this fuse link but It is possible it could short the fuse if it is mishandled. Hope this helps and good luck.

I have heard to do several things can you tell me is there a specific fuse for the heater blower? Mine does not blow anymore actually the whole thing does not work. If I turn the temperature gauge to cool temperature the cool air does come through chilled and only by delivery of the vent not through the blower.

Hi 2carpros,
The heater fan is not working. Once in a blue moon, it will come on. Which leaves me to think that it is just an electrical problem, maybe a short somewhere. I will look to here from you. Thanks!

Where is the blower motor located on this vehicle? Please keep in mind, that I am a novice. Thanks

I have found the case but I know there is an easier way to replace the blower motor. Can you help?
Can we go through the cowl in front by the wiper motor or do we need to go under/behind the dash?

I have replaced the blower motor on a 1990 300e. It is not difficult. The Mercedes mechanic wanted to charge me $1,000.17 to replace the blower motor. After having done it once, ( I put the motor in backwards!) I redid it and it took seventeen minutes to expose the blower motor. I now no longer use this mechanic. You access the blower motor by taking the windshield wiper motor off completely. Remember where every bolt goes. Take the windshield wiper armature off intact. It helps to always place the parts on the same side of the car when you take them off and in the same orientation. There are silver clips that hold the blower motor housing on that need to be pushed off and they must go back on or the fan will always have a rattle/buzz. Ask me how I know that). Before buttoning it up, it is a good idea to turn the A/C on and test the fan. Make sure the squirrel cages are spinning in the correct direction. I tested mine before closing things up and attributed the lesser air-flow to the fact that I had not yet put the top of the blower fan housing on. I was wrong. The silver clips I spoke about earlier are located all along the front and sides as well as two hidden ones on the back that you really will not know about unless you have done this before. Also, put a towel in the bottom of the plastic deck just below the windshield wiper. You will lose a screw or two down that bottomless air ducting if you do not. (Ask me how I know that as well) also, I used only hand tools. Nothing electric or air powered. A real mechanic with those tools could most likely replace that motor in thirty minutes or even less. And careful with the windshield wiper blade armature. I think it would be fairly easy to crack a windshield. Hope this helps and good luck.
