Default Cooling fans staying on..

So in the last week this has started. It's never happened before in the year and a bit that I've owned the car. Lately when I park my car and it is at normal running temperature the cooling fans will come on (normal..obviously) but they will stay on after I park the car.

Then today I parked the car, turned it off and the fans weren't on. About 5-10 minutes later I heard them turn on and I stood there listening for a few minutes and they would turn on and off periodically for about 10-15 minutes.

Now it's not exactly warm here in the winter and I've done 4 hour road trips at 70mph in 80 degree weather and never experienced this before. Is this normal?

Possibly...but once the car is shut off should the power to the fans not be shut off as well?

That's what I thought at first but that doesn't explain why the fans come on when the car shuts off. My thoughts are leaning towards the fan switch itself.

Geezir,

I have had a strange cooling fan issue with my 2003 1.8t since i bought it back in August. First of all, while doing a coolant flush, I saw that my large of 2 cooling fans was unplugged completely. (get to that later) But what my car does, is no matter what temp is outside, how long or hard i drive it, no matter what coolant temp is reading, my fans will turn on the second i start my car, actually i dont even have to actually "start" the car, i just switch key into first position and they click on. and stay on the entire time. Then no matter how long i drive my car, for 2 minutes, or 2 hours, once i shut off my car they stay on for a good 8-10 minutes before clicking off.

Now so far, I have replaced fan relay switch, old black coolant temp sensor with revised green top cts, the fan thermo switch on radiator. STILL they are doing the same thing. I just got a new fan control module I plan on putting in next time weather is nice. If this doesnt fix whats going on i dont know what to try next. Maybe we can work this out together, I will let you know what happens when i put in my new fan control module. Hope this helps.

Definitely let me know if it works! Out of curiosity how much did the fan control module cost you?

20thGTI,

nope no CELs or any codes. and Geezir no problem, I am going crazy trying to figure this out. I dont know if all this is related but A/C is and has been since I got the car, blowing warm air. The clutch on the compressor is not engaging. For this I have replaced a/c relay, replaced a/c condenser, radiator (bc upon looking under my car, i noticed they were damaged) and evacuated and recharged system. But as for the fan control module, I bought it in the VW classifieds on vortex for $50, brand new OEM is around $175...

Lets fix this!!! lol

Hmmm...I think we might have found common ground here. My car was in an accident about 2.5 months ago (deer, ditch, tree..not pretty). Anyways that AC condensor was cracked and let all the pressure out of the system. I have yet to recharge the system as I don't have cash for the dryer canister right now.

Got a picture of what the fan control module looks like? I'm wondering if it was damaged in the accident.
