You are talking about the main engine fan, right? It runs and my car does not overheat - even with A/C on and in this 90 degree heat, car runs a little over 80 degrees C on the dash gauge.

How would I check the clutch?

What do you mean 'blocked'? The temp switch just screws right into the drier - nothing blocking it.
