Default Aux fan issues. Ideas?

I've searched & can't find anything that fits the issues I'm having, at least not of the pre95 models.

I've a 91 Limited 4x4. Shes started getting hot (not boiling over tho) when I drive around town or sit idle for more than a minute or 2. My aux fan doesn't seem to be turn on. I'm going to run wires from the battery to it to see if its a wiring issue or if the fan itself is bad, so heres my question -

If the fan is bad, should I just replace it & wire it as is or wire it to a toggle switch?

Any suggestions to keep my temp down?

I had the same problem, and I just went ahead and put a toggle switch on mine, that way when I'm wheeling or idling I can just turn it on and know that it's working

My husband swears it has no fan clutch. He says its the electric aux fan. I call it the radiator fan because its the one right in front of the radiator.

You should have 2 fans. The primary, which is a mechanical fan with a fan clutch and a secondary or Aux. fan, which is an electric fan.
