Hello!
I replaced the auxiliary fan with one from Europa parts and about two months later, the fan just started going crazy fast intermittently. The car is not over heating or any other issues. I change to Econ, cold, hot and just it continues to run very fast and its noisy till I turn the car off. Sometimes will go off and start again during drive time. I tried to replace the aux relay under the dash (4H0-951-253-A), but I can't tell which relay is for Aux. There are like three 40 amp relays. Temp sensor was replaced a while back. In the morning the fan will not act up, perhaps, until it reaches running temperature. Again, this comes and goes. I can see the aux fan running when I run the heat, but I just cant figure why it gets crazy fast for no reason.
Also, while I was looking into the relays, I saw the A/C Clutch Control Relay (443919578C). When I keep pressing the Econ button on and off you can tell it puts pressure on the system and I can hear a clicking noise and a small spark coming from it. I took it off, opened it and it looks that its all is good. There was little residue between the two pieces that touch. Is it normal for the A/C relay to make this clicking noise? Also, do you know which slot is for the aux relay?
Thank you for the help and direction.[headbang]
