W126 power window question
All four power windows failed today on my 1983 300SD. Fuses are O.K. Any quick fix ideas?

I never say anything is impossible, but this makes no sense. The windows have two separate circuits feeding them in a diagonal arrangement.
Does everything else work on the vehicle? Is the engine running when you do the test? Edited: Go directly to post #14 and perform the test. Last edited by Brian Carlton; 09-06-2005 at 12:26 AM. Reason: new info after further discussion |

i think there
may be additional fuses other than in the fuse panel. perhaps in the consol somewhere. i have not changed them myself but my indy has.

How old are the fuses?
My windows would stop working at random before I installed new fuses. It was odd.

I don't know of any fuses for the windows other than the fuse box. Wouldn't make any sense to have two fuses in series. |

Maybe I'm totally off base here, but isn't there a relay behind the instrument cluster for the windows? Perhaps this failed?

Is it possible that there is a break in the elctrical supply BEFORE it gets to the fuse panel?
On some "other" cars, the accesory circuts in the ignition switch have different contacts than the engine "on" contacts--if that is the case, it is possible that wiggling the key switch may make the windows work. |

Hook up a voltmeter and check for 12V at both fuses that operate the power windows. |

From what i remember... there is a connector right behind the panel to the right of your gas pedal check if that's connected fully.

This must therefore be the first thing to check. See if there is 12V at the two fuses (a and b ??) with the engine running. |
