Like you said check your fuses and see if on the fan area if any plug came disconnected. If all is good see if you can get it scanned by vagcom (preffered method) or a scanner and see if there are any codes that get show up. Post back here with any results.

check fuse, relay, power at plugs

you can jump the plug to make sure the fans work

Re: Rad fans won't shut off help!!!

Also keep in mind this happened after having the car on the road for 1 day I bought it 2 months ago and put it on the road for summer I got a sweet deal on brand new fans and shroud for $210+$150 install but I want to put my H&R and Bilistein's on and dont want any more fan issues

I work on the fans for a B5 passat and the relay was under the dash

IIRC there is fan module somewhere

So I brought it to my mechanic who was a vw tech for 15 years at the dealer the fans dont have a relay its the module and the module is in the fan shroud he basically hookrd it up to the laptop and checked the temp sensor it was fine also checked the fuse panel for water damage he sprayed air into it its fine the only thing we came up with is the module is bad on the fans but since that trip it has been turning on and off proper so i'm hoping it continues to be OK
