The cooling fans on our 2004 Volkswagon Touareg remain on for a long time even after the ignition is turned off and regardless of how long we drove it. Would replacing the thermostat fix this problem?

try turning the key at the same time as pulling it out

Wrong place to ask

You need to go to the VW Dealer
Parts Counter, with your VIN #

It's probably a bad fan switch. There are two sensors in your cooling system. One is the one that your dashboard reads, the other is the one that turns your fan on and off. If your fan switch is bad, it will make your fan stay on too long or when it doesn't need to be on. Good luck.

change your thermostat ad you should be good

Find the radiator fan relay and remove it. If the fan stops, source a replacement relay.

try replacing the resistor for the fan

"Already had replaced: both cooling fans, fan control module, coolant temp sensor, fan switch, 4 terminal connectors. No trouble codes reported in VW electronic diagnostic test. 2 different VW dealers and and my mechanic threw in the towel. Any suggestions greatly appreciated."

This is a common problem with the VW..and no one has an answer WHY. (including VW mechanics)

THIS IS A RECALL ISSUE and should be implemented

Follow the BIG water line comein from the rad on the top itll go into a housing in their is the thermostat

Check the fan thermostat(s) - it(they) should be near the radiator. BE CAREFUL - these fans can start at any time!!!

Once you turn the octagon screw to release the light and push it forward or out of the front of the vehicle, take a light and look to the left side if your working on the driver side or the right side if your working on the passenger side and you will see a metal tab release. Take a long flat head screw driver and press down toward the ground gently. The headlight will be released and the whole assembly comes out as it has a plug/electrical connection on the back of the assembly. I just replaced my headlights, I have a 2004 Touareg with 44,000 miles and have already gone through 2 sets of headlights. The VW dealer will want $300.00 to replace 1 side! They have lost their minds. How long have you had yours and what engine do you have? Just curious if you have had any problems? My Touareg has just needed tires, brakes, headlights. I have done the brakes as well. They want around $900.00 + for front plus about 8 for the rear. If you need anything just hollar and if you have any questions just let me know if I canhelp.
