Where can I find the radiator fan cooling relay ina2000 AudiA6 Quattro VP

Engine Cooling Fan Relay 1
In the center front of the engine compartment, on the lower radiator support, near the cooling fans
Engine Cooling Fan Relay 2
In the center front of the engine compartment, on the lower radiator support, near the cooling fans
Engine Cooling Fan Relay 3
In the center front of the engine compartment, on the lower radiator support, near the cooling fans

radiator fan switch ???? has relays ,high speed cooling fan relay an engine cooling fan relay an a cooling fan resistor . A coolant temp. sensor . The temp sensor is a input to the PCM - engine computer ,when temp gets to hot the PCM energizes the relays . There is no radiator fan switch . Videos on youtube . http://www.bbbind.com/free_tsb.html check out wiring diagram here .

no idea to be honest earlier jeeps had then at the front of the wing down below as i remember ?? newer one would i imagine be in the electrical box under the bonnet near the battery

overheats at idle only are typically the fan system. Cars use the fan to pull air across the radiator for cooling. Any speed over 10 mph there is more than enough natural wind to do this without a fan. If the problem immediately goes away when you start moving, it is probably a malfunction or issue with the fan. I have on more than 1 occaision had a customer tell me they had the fan replaced and car was still overheating, and it ended up thje fan was spinning backwards or not turning on because of a fuse or relay issue.

If it doesnt cool down fully once speed is above 20mph for more than 30 seconds, there may be other issues like plugged radiator or weak water pump impellars. water pump is a fan that moves water instead of the air. if the blades wear, they still kinda work, but at idle they work poorly because the broken blades only move a little air at low speed, rev the engine up, they spin faster and work better. If the fan is functioning OK (Turns on and off by itself) and car still runs warmer at idle than at rev, water pump may be worth investigation.

It can be faulty fan relay.The relay is not turning the system off.Or its wire short issue.Even with ignition off ,the fan relay is getting power so its not letting the fan to turn off.Bypass the fan control relay and see if still the fan works with ignition off or not.

Thanks.

Fan relay is located under pass headlight. Remove light assembly, use 2 1/2 " hole saw to drill hole in plastic housing ,3"from back wall, 3'' from left side.This will put you right over relay. Unscrew two bolts,replace. Relay was $40.... dealer wanted$350 to remove front bumper to replace it.

check your sensor that controls the cooling fans.may need to be replaced.
