Is there a resistor in the condenser motor fan circuit?
I didn't know that there was one!

What he said!
I went out and had a look at my cars and darned if you're not right!
I thought that it was the fusible link but it's definitely not.
I ohm'd it out with a good quality meter and it measured about 0.1 ohm. It's hard to be more accurate. Then I got a good photo of the part and it appears to be 0.13 Ohm (130 mOhm).
It's obviously 0.13 Ohms and if I were to guess from the shape it's probably a wire wound ceramic cement encased power resister rated at about 1 to 5 Watts.
They are reasonably uncommon. I would imagine that something like:

RES 0.13 OHM 5W 1% AXIAL
130 mOhms ±1% 5W Through Hole Resistor Axial Flame Retardant Coating, Pulse Withstanding, Safety Wirewound
would work. They are quite inexpensive at US$1.24 each.
You would have to make it weather resistant by shrink wrapping it or some other means. I would order a few of them and try to use them before making a permanent enclosure to see how hot they get. If they run really hot, by wrapping them you could make them run even hotter and possibly run the risk of them catching fire!
The current flow through the resistor will determine the actual wattage dissipation. The motor resistance plus the 0.13 ohm of the resistor will set the current flow.
12.6V / Total resistance (0.13 plus motor resistance) =Circuit current flow.
Power dissipation is (I x I)/R where I is current in Amps and R is the 0.13 Ohms of the Resistor
(help me out here guys - I'm REALLY rusty doing these calculations!)
I could actually go out and measure the circuit resistance, but i put the plastic cover back in place and I'm too lazy to take it off again. Sigh.
Let us know what you try.
