I have read several other posts regarding this issue and I came up with several possible causes.
I was cleaning the UIM using Big Jim's method. Everything worked great except when I noticed my radiator fan kicked on for about 10 seconds and then shut-off. I looked at the temp gauge in the car and it was in between the "M-A" in normal. I dont think it cooled down in that short of a period. The fan just won't stay on.
I replaced the ECT and thermostat about a year ago. Could it be a relay? Are there two fan speeds? I only hear the fan when the A/C is on. The car runs a little warm when the A/C is off. Is there a way to test the fan speeds?
