I assume from your description that the fan will run until the battery is dead?

Sounds like your fan control relay (underhood, large fuse panel/box) or fan control switch is stuck. Both very simple to replace.

Fan control relay

Fan control switch

I hope this helps

    I can't see any thing that says fan relay... is there a short form for it or something?

1993 audi 90cs is overheating fast and I don't think the fan is coming on! What do I do?

First of all check the fan fuse to c if it's ok if it is then replace your fan switch on the side of the radiator cause that tells the fan when to come and it's a common fault on most vw cars if all else fails u will need to test and c if the fan is still working,u can check that by either putting direct power to the fans wiring if it does work then change the thermostat

Why is my 1993 Audi 90cs overheating?

There are dozens of possibilities from as simple as a bad pressure cap or low coolant level to as bad as a cracked engine block. Knowing the conditions that cause the overheat would help diagnose, here's some basics--assuming the coolant is full. Only overheats at low speed is generally an airflow problem: fan not running because of a fuse, relay, temperature switch, or dead fan motor. Only overheats at high speed is generally a coolant flow problem: radiator is plugged up, faulty thermostat, water pump vanes damaged. Tell us anything you've checked, any recent repairs done, and the conditions under which it overheats.

1993 audi 80 1.9 tdi cooling fans not connected

You won't know which until you check. Unlikely the wires. Fuse or sencer most likely. Check the large fuses first. If it is the fuse then check the wires as somthing the matter with them or the fan itself. Turn the fan with your hand (with engine turned off.) it should turn freely. If all this is ok then you need a senser.

My radiator fan is not working. the radiato fan relay and the relay for radiator fan (speed 1) are not in the car. do i need to put them in for it to work or what other problems could it be?

I think you are talking about the radiator fan for the coolant in first place and than about the heater fan (speed 1)? If yes than first thing is to get the relay in for the radiator fan as it will not cool your coolant liquid and will cause the engine to overheat, with the second one it is a faulty resistor inside the vent and that is why you don't have the first speed, unless the pollen filter is dirty and the first gear cannot actually **** enough air.

My 1995 audi 90 wont stop overheating

It sounds like you have a head gascet fault, if the water hoses are highly presurised with back pressure when car is running and you are lousing water, creamy coloured oil then these are all symptoms.
some audi's have platic water pump fins that deteriorate too this also could be a fault,
A pressure test on the cooling system should conferm what exactily is wrong.
