I have been looking at a 1993 Mercedes-Benz 190 E 2.3 liter, that is for sale. The man selling it does not seem to know anything about the car. I am a unusual car junkie (think Peugeot)that has a hard time in the USA. I am really interested in this car. He says it has a problem it has all the power in the world until you turn on the heater. Then the engine starts to make a lot of noise and you lose all your power. Can anyone help me? |

Hi and welcome to the forum, I'm no expert but sounds like someone has been fiddling with the wiring.

Hello and welcome. That's an odd problem. I can't say I've ever come across that before. |

does it have AC? ac will reduce the power of most cars when in use (to the point where its laughable in some cars! so i can imagin the 2.3 8v struggling if thats the case) however the noise shouldn't be there so im guessing an issue with the AC?

My husband is thinking it could be a vacuum line. But he has not seen the car yet. Could that be possible? Some one else told me check the heater fuse?

Are you certain the noise is coming from the engine? The fan motors in these cars are known for wearing out the bearings. When they go they make a hell of a noise. A bit like a Huey helicopter. But that wouldn't explain the loss of power. The heater dials are controlled by vacuum but not the heater switch or motor. |

Another thought. Maybe it's the alternator packing in? When the heater motor is turned on extra load is put on the alternator? |

the ac will only lag the motor down so much. because the compressor has a speed sensor that cuts it off if its not running fast enough. and think about the couple of things that cut on whne you hit heat that pump, blower motor, depending on setting compressor is suppose to run. can sit here all day and try to diagnose a problem thats why we charge 79.99 at cool car just so many questions that could be asked, things to be implied, and then i cant even look at anything to give n answer have you driven it down the road atleast? is it just heat being cut on that causes this or other electrical functions? have you noticed any re wiring a bad ground or lack of one to something someone redid or rigged up would cause such spiratic problems bottom line its really a crapshoot without it in front of me bein such a funny problem |

I feel like I need to apologize, I'm so sorry. I'm just a girl who likes cars that stand out in a crowd. I didn't mean to upset or bother anyone. |

No need whatsoever to appologise, this is a friendly forum and I would be unhappy to think you werent made to feel welcome. We all try to pull together and find the solutions to problems. Sometimes this process can sometimes be a slow one but we usually get there in the end and save the member some hard earned money. |

The problem you describe could be a 12 volt system earth problem, switching on other circuits may take power from the ignition system causing loss of power. Try switching on other systems to see if the problem transfers. |

Hi and welcome Janee Would it be possible for you to post a video clip of the car running to show the problem ? There are no stupid questions only stupid answers.

Hmmm, this is interesting problem... First of all, a M102 engine dose not lose power due to bad earth, then it shouldn't start properly.... When you say itīs loses power when ac is turn on, i would start to check the A/C compressor and its magnetic clutch... Or to be clear, i believe its the compressor! =bad or broken bearings inside. OR forget all above... HEATER you wrote Disconect the alternator cable (three cables in front of the battery) Start the engine turn on heater.... what happens?
