HEADACHE WITH AC/blower etc! w126
Well, about 2 months ago, i was driving i had my heater/blower on since it was cold ( it was on economy at full blast). My ac was not working because it did not have freon. All of a suddent as i was driving, the thing that blows air into the vents stopped. I was almost home so i figured ill check it out tomorrow.
Well fast forward, it has never been working again. No more air from the vents. Now i want to fix my AC, my compressor does not engage, my blower does not blow, i took off the blower ( the thing that spins on the passanger side) and i took off the wires, and put it on my electric read out ( a light bulp) it did not light up. I went to the front of the compressor, did the same, nothing, i checked rellays, nothing. Where else should i check ? this thing is driving me crazy! I would like to get this fixed before summer school starts. I would appriciate any advice/tips on how to check whats working and wahts not. So far it seems like my : Blower does not work AC compressor does not engage Fan infront of the condensor does not engage So im guessing something is mest up with the cooling/heating system--but i have no idea what! Thanks guys before i g o ![]() |

I had a number of electrical issues in my 300SD that completely went away with new fuses. They are cheap and will save you a ton of headaches. |

i just went out to do as you said
I replaced all the blue ones Red ones and about 75% of the white ones I ran that light bulp thing to see if it was getting current... its weird If i have the positive thing touching one fuse and touch the same fuse- it dosent light up, if lights up with only some of them that i touch ( other then the one im touching with the positive side) is that the way it should work? |

Is the key in RUN? Some circuits aren't live when the key's out.

Better than a light bulb would be an VOM to measure the conductivity/resistance of the fuse. Additionally if your only getting 2v at the end of your circuit it might be enough to light your bulb yet not tell you your missing 10v of power. You can get a cheapie at radio shack for $10. Just for future reliability I would finish the rest of the fuse box as it will save a lot of future headaches. |

I do a lot of DIY work but recognize there is distinct line that I don't cross when it comes to projects I don't understand fully. There are a lot of backyard mechanics that jump right into jobs that are too complicated for them without doing the research and end up damaging their cars in the long run. I wish you the best of luck and hopefully its a cheap repair. |
