Hi all, having some issues with the rad fan not kicking in on my 200. Was crawling through car park traffic, then the guage creeps past the 3rd line from the bottom. So about 90 degrees.
Usually it’ll sit here fine and maintain its temp, but it crept past and got up to the 4th line. Soon as I saw it I turned car off, tried to force fan on with AC but it wouldn’t come on. (Picture of overheating and then where temp usually sits attached)
Got back. Pulled the 40a fuse from the front of the battery for the fan. All intact, no breaks. And then I pulled the purple fan relay, had a slight bit of blue dust on pin 5. Cleaned up, back in. Now fan works with the AC. Whether it’s low speed or high I can’t tell. But it won’t kick in when car is up to temp. Help! Have ordered the low speed thermal resistor that fails on the bottom of the fan, and a new purple relay. Unplugged CTS and fan comes on fine.
What else can I check? Coolant level etc is all fine, thermostat is fine too. Guage comes up then settles just below once fully warmed.
