: Check the wires that run from thermostat, there is a sensor there and the wires tend to dry up and break off. I have this problem on my 88 right now and plan on trying to fix it this weekend. Good luck

There's a repair kit for this pesky aux fan switch. The cars came with the wiring too short and that's why they dry up and tear. You basically take 3 new ends from the repair kit and take apart the connector. Reassemble the connector with the new ends and splice into the existing wiring, bingo! done. If you guys want the part numbers I'll pass them along once I'm home.

As far as bleeding the system, I'm not aware of a bleed screw anywhere. Our reservoir is high mounted so I assume it does not need to be bled. I'd appreciate more info on this as I have to change my coolant soon. I'm going to put a new thermostat in while I'm at it, could this be your problem?
