No radiator fans, need some brain storm power!
 

Neither the low or the high speed fans will come on in my 92. If I jump the pins at the temp sensor harness the fans come on just fine. Are there other possibilities or does this mean my sensor is bad/blocked?

Test for continuity at the switch when you believe it is hot enough that it should come on.

I'd say bad temp sensor in the radiotor since you do actually have power present.

Recently I faced the same problem, replaced the switch-no help, replaced thermostat-problem solved.

The temps stay normal when the car is moving.

I'd check the bottom sensor in the radiator. If you have corrosion it could get blocked, mine did.
