You seem to have solved your own problem, I dare say--- You could check coolant level and thermostat behavior as it relates to engine temperature~ Seem like it's easy to get to? a lot of these are conveniently bascially c-flange arrangements and only take a moment to replace. Tell me that this is one of those easy to replace models....else will be turning to u-tube with checkered results-

It could be a worn water pump that is not circulating the coolant at low engine speeds.

If all of your blower fan speeds work, your resister is good.
