89 audi 100, fan problems
Ok, My 89 audi is having some probelms. I think it was yesterday, i
pulled into my driveway after work and noticed the fan, the one right behind the radiator, wasn't stopping. I figured that it would stop within 5-10 minutes. I came back out 15 minutes later and the fan was still running. I started my vehicle to make sure the battery wouldn't die, and then turned off my car again. Once again i waited for another 15 minutes, with the car off, but the fan kept on runnning. So now whenever i want to drive my car i have to pull the battery so the fan will stop. Please any ideas will help. Thank you, Jimmie |

I can't remember if it has a seperate switch or whether it's done through the tmeprature sender, but look down on the radiator and see if you can find an item with two wires leading to it. Unplug it and the fan should stop. If that doesn't work, it's probably a stuck relay - have a look at the relay listing panel and see if there's one that does the fan. Tap it a few times to see if it unsticks. -- Skipweasel. Ivor Cutler - "Never knowingly understood." |

No what does this switch look like? Sorry im not very mechanical. Does
it look like a light switch or a toggle switch? Jimmie |

Re: 89 audi 100, fan problems
The fan thermo switch is located on the back of the radiator just below the
lower radiator hose. three wire connection for fan speeds 2 and 3. Still I would be more inclined to check the relays first. Relays for fan speeds 1 and 2 are located int he main relay / fuse box buy the drivers side hood hinge. Fan speed 3 relay is located in the AUX panel under the dash by the driver's left knee. Large and very difficult to pull due to its large conductors to carry the amperage needed for the fast speed. I would suspect either fan speed 1 or 2 relays to be the more likely culprit.

Re: 89 audi 100, fan problems
So do you recommend unplugging the switch while the fan is running, or
when i have the battery unplugged? Thank you, Jimmie |

Re: 89 audi 100, fan problems
Because I feel that the relays are the problem I do not see a reason to unplug
the switch. The switch is used to activate the relays which then power the fan so unplugging the switch will not have any effect if my theory is right. I would look to the relays first and you can check them with the battery hooked up. If you still want to unplug the switch you should disconnect the battery first because it is located within inches of the fan and you do not want to be anywhere near that when it is running.

Re: 89 audi 100, fan problems
I was guessing that he would replace the relay with a known good one. Still,
your point is correct. I would, however, not recommend unplugging the switch with the fan running. Agree on the second point as well.
