I "bridged" the heat and AC hoses until I replace the heat module in my Jeep and the connector (bridge) has broken twice this week. Thoughts?
Done so , far far from home, many times, hoses ruptured.
i think you meant the heater core hoses leaked
so I bypassed them with new hose.
some do this on warm tropical islands and run like that for ever
in fact , my first car a 1964 dodge, it was on option (heat)
there are exceptions, on some cars, as the hose feeds the thermostat base in this very odd way, (rice cars)
but not this car.
this the 4.0L ?

The lower speeds are controlled by a resistor block. That's what needs to be replace. It's usually located next to the blower. It will have electrical wires connected to it. High speed bypasses the block so it alway works.
If you want to replace it then;
) Disconnect the battery negative terminal if the vehicle have air bags. Wait 2 minutes for system to discharge.
) Remove the kick block on the passenger side.
)Remve the glove box
) Remove the bolts holding the blower motor resistor. Push the red lock up and press down on the click
) Pull the block out.
) Install new block and reverse steps above.

Yes i would check if your radiator fin turns on when the engine gets warm.
Most likely thats the cause.

As soon as the vehicle reaches around 180/195 (depends on the temp of the t-stat) the thermostat should open and thereby filling the top hose with warm/hot water.
Are you sure the thermostat is facing the right direction? Is the cooling system full?
Here is what you can do: remove the t-stat, replace any lost coolant/water and run the vehicle with heater on full blast for about 15 minutes or until the temp gauge is showing about halfway. During this time be sure to monitor the coolant level in the reservoir.
If you still have no hot air you may have a blockage or perhaps the heater hoses are not even connected.

Put an small brass butterfly valve in the heater line, on both sides. That will turn it off for the summer, and you can turn it on for winter. Alternatively, you could try and do like I'm doing on my '59 Chevy, when I get it out of the flood plain, and route ice water through the heater core.

Blower Motor Resistor and Controller Replacement Image Blower Motor Resistor Or Controller/Power Module Remove/Install REMOVAL 1. Disconnect and isolate the batten' negative cable. 2. Depress locking tab and unplug the wire harness connector
from the blower motor resistor or controller (power module). 3. Depress locking tab and unplug the resistor or controller
connector from the blower motor. 4. Remove the 2 screws that secure the blower motor resistor
or controller to the heater-AC housing. 5. Remove the blower motor resistor or controller from the
heater AC housing. INSTALLATION 1. Install the blower motor resistor or controller to the
heater AC housing. The housing is indexed to allow (controller power module)
mounting in only one position. Tighten the mounting screws to 2.2 Nm(20 in.
Lbs.). 2. Plug in the wire harness connector to the blower motor
resistor or controller. 3. Plug in the connector from the blower motor resistor or
controller to the blower motor. 4. Connect the batten' negative cable.
