Today I noticed my heater is not putting out much heat, so I was looking under the hood and noticed these two unhooked connectors. I realize they don’t have anything to do with my heater issues, but I also have no idea what they go to. They are basically rubber boots with an electrical connection in the bottom that runs to a wire loom. Any ideas?

Look like brake fluid sensor wires from the bottom of the master cylinder.

Year Model Market Look with in reach and see if there is a place to plug them on. Then go to the correct wiring diagram. Look for single red or orange wire with the correct stripe.

So is the heater valve open? Perhaps there is an air bubble in the heater core. Core is plugged with stop leak from a PO.
