UNDER BLACK valve cover on ORANGE cylinder head behind the metal tube is the location of the fan sensor switch. It's that dark circle you unotice.
EVERY SINGLE RWD 60* cylinder has this hole.
This is a 1995 F Body 3.4 cylinder, too.
For our 3rd Gen F Body this is the location of the fan sensor switch.
IF no sensor there, you have a problem.
IF no single wire with spade female terminal for this sensor you have a problem.
IF that hole covered with a plug, you have a BIG problem.
The engine needs to be outta car for a plug removal, as it's next to impossible to access for any leverage.
Hope this leads you to the solution.
Serious, this is all the truth, ask at GM parts counter for print out & parts list for confirmation.
