98 XJ sport. Auto 4.0L 4X4.
My Aux fan works well with the AC on. But when the temp reaches slightly above 210 on the gauge the fan stops running. And it will not come back on again till the engine is off and cools down below 210. But once it goes over 210 (sitting in traffic) the aux fan will not run.
Could this be a CTS (coolant temp sensor) issue? I unplugged it while the XJ was running and plugged it back in and the fan still didn't work. But it did set off the "check engine" light. Thats to be expected. I know the light is on because I unplugged the CTS while the thing was running. I don't care about that, I care about the fan not coming on above 210. I let it sit and get really hot (225-230 degrees) and the fan still didn't trigger on.
Any ideas?
PS I already replaced the relay today. That didn't do the trick.
