If you're hitting your gas and the temp changes, then yes you have some sort of issue with the temp sensor. However, your fans should come on if your AC comes on. Now the question is- does the AC work? If the AC doesn't work- like from low pressure- then the circuit isn't complete, and the fans aren't turned on.

Fix your valve cover gasket and replace your temp sender- see what happens. It doesn't seem like you're figuring anything out from all this testing and questioning.

If you still want to test stuff, then if I were you I'd do a continuity test on the negative to make sure it's connected somewhere. You should show .1 ohms if it doesn't read 0.0 ohms. You can also test the fan diodes which are in the fuse box. That's the backwards arrow symbol on your schematic. You should get continuity with one polarity, and open circuit with the other polarity. I would think that the ground connection was lost before you lost both diodes.
