Just wondering if anyone has run into anything like this...I'll put some background down at the bottom in case anyone feels like being generous lol.
Anyway, the blower motor in this 09 Dodge Grand Caravan works fine on settings 1, 2, 3...but does NOT work on setting 4 (which is high).
This vehicle does not have Automatic Air, or rear air. The wiring diagram I can get at work shows 5 wires going to the resistor, but there are only 4.

And here's the info:
Resistor tested ok -- all 4 pins have continuity. Which, according to mitchell, means it is good.
Prong 1 of the resistor has 12.6 volts at all times -- blower motor at 0, 1, 2, 3, and 4.
Apparently the switch controls which resistors the blower motor passes through. On 1, it passes through 3 of the resistors. On 2, it passes through 2 of the resistors. On 3, it passes through 1 of the resistors.
At the blower motor itself, I get 12.6 volts on setting 1, 12.6 on 2, 12.6 on 3, and 0.00 on setting 4.

Any ideas? And yes, it is a fleet vehicle, out of warranty, so I am stuck with it.
