Hi all hope you're all doing well. I have a 2003 convertible beetle 2.0. So far have replace the y shaped cooling flange that blew out, water pump, timing belt, plugs, coil pack, overflow reservoir, and ECT sensor. I am still having issues with the car getting hot so I decided to run a flush/cleaner through the cooling system in case I had any blockages. While I was running the engine for the 20 minutes with the flush in I noticed that the cooling fans were not kicking on and never did. So I turned on the ac to see if they would still auto kick on with the AC and they did taking the temps back down. But I'm wondering where to start with figuring out why they wouldn't come on normally. So far my thoughts are maybe thermostat is stuck closed so the radiator fan switch is not triggering or the radiator fan switch sensor is bad. What do you guys think maybe a fuse or relay? I know I had to replace the coil pack because it got soaked when the flange blew out. Any advice appreciated. Thank you.
