Been noticing my radiator cooling fans have been running at unusual times
Normally the fans will kick on at about 220* then turn off at 200*.
Lately I have been noticing them coming on at about 190*. Other temps too. One time the fans were running after I shut the engine off, key removed. This is when I really started paying attention to this issue. Then, now that I am paying very close attn to the fans, I noticed that the AC compressor clutch was engaging/disengaging on it's own. On for 3 seconds, off for 10 seconds. Something like that. And the fans were coming and going too but not exactly at the same intervals as the AC clutch engagement. I thought to myself, OK, the AC issue is causing my fan issue perhaps since the fans come on when the AC is on. Any idea what is causing this? |

Does the AC clutch engage when defrost is on yet outside temp is above a certain temp? I did do have this on when its warmish outside.
Any other situations where the AC clutch engages when I have not set the HVAC knob to AC? BTW, not noticing any cool air out the vents. I simply hear the engine RPM drop in response to the AC clutch engaging and once this caught my attention I shined a flashlight at the compressor and watched it closely to confirm my suspicion. |
