With the blower switch knob set to the M2 position . You should have continuity between 2 and 4 (this should be at or less than 5 Ohms). With the blower switch knob set to the HI position . You should have continuity between 2 and 1 (this should be at or less than 5 Ohms).
How can I test the blower motor switch?
This is good and is the correct and expected test result that tells you that the blower fan switch (in the A/C-Heater control panel) is NOT defective. Your next step is to bypass the blower resistor using a simple jumper wire. For this test go to: TEST 2: Using A Jumper Wire To Bypass The Blower Switch.
