what the heck does the $300 "resistor" do?
Have a bad blower motor in my 93 300d 2.5 turbo. was advised to replace the triangular resistor also. what does the resistor do for that much money??

it takes space and time and converts it into a signal your ACC system can understand???
lucky guess |

modulates the blower motor speed?
that's all i got

It houses a 3" tall gremlin that telepathically controls the blower's speed.
Gremlins aren't cheap to breed. |

As soon as I posted, I thought, uh-oh, boy I am going to get some wise ass answers. But, the new one does resist, and if I list the car for sale I can always say, "The resistor has been replaced"...

i would have found out what style resistor and went down to Radio Shack (after an hour of telling the noob what I need and where he can order it from his computer.. jeeze I rember the days when you could go into RS and order a type 54-z`1 FET chip or w/e and they will offer you 5 kinds)
and replaced it with the non MB star christened one |

You can still log on to www.tubesandmore.com and order a part similar to this for a lot less! It's just a high power wire wound voltage divider network for regulating the blower motor speed and a means of cushioning electrical spikes! By the way, a $300.00 resistor WILL protect a $125.00 motor by blowing first!

Sometimes auto salvage places are very attractive. It almost has to be more than just a voltage divider network for that kind of money. On second thought maybe not with todays prices and marketing.

If it's not too much trouble, Knightrider
What is the number of the resistor that would replace the 92 Benz 2.5 one?
None of these products resemble it in the least. I think this is the aluminum "porcupine" that sits below the wiper motor. Thank you ever so much.

There might be one wire wound resistor with adjustable variable tap points available in a larger wattage unit. More likely you would wire several heavy wire wound resistors in series taking the various taps off at the junction points. If anyone can post the resistance values on each leg and the wattage requirements it should be possible to duplicate. I still like the ideal of say ten dollars at a pick and pull or a salvage yard that is reasonable. Military surplus stores used to be a good source of the larger wire wound resistors as well. I suspect the original design also has a heat sink incorporated .

the resistor for the w123 ACC cost 357$... damn.. I'm going to pull all that I can find. The guy at the desk will be like.. what is it? I'll be like.. uhhh german ashtray?
