TEST 4: Testing The Blower Switch Speed 4 (HI) Circuit
Now we're gonna' test the speed 4 (HI) circuit inside the blower control switch.
The wire that connects to the speed 4 (HI) circuit is the black with tan stripe (BLK/TAN) wire of the blower resistor assembly's connector and its labeled with the number 2 in the photo above.
If all is OK with this circuit inside the blower control switch, then your 12 Volt test light should light up when back-probing the terminal (that connects to the BLK/TAN wire).
If the test light does not light up then you can conclude that the blower control switch is bad and needs to be replaced.
These are the test steps:
- 1
Disconnect the blower resistor from its electrical connector.
- 2
Select blower motor speed 4 on the AC/Heater Control Panel.
- 3
Connect the 12 Volt test light's alligator clip to the positive (+) battery jump start terminal in the engine compartment.
The positive (+) jump start terminal is on the under-hood fuse box (see photo 2 of 2 of TEST 1). - 4
Back probe the terminal that connects to the BLK/TAN wire of the resistor block's connector with the metallic point of your 12 Volt test light (see photo above).
NOTE: Avoid probing the front of the female terminal of the connector or you run the risk of damaging it with the tip of the 12 Volt test light. - 5
The 12 Volt test light should come on if the speed 4 (HI) circuit is OK.
Let's analyze your test result:
CASE 1: The 12 Volt test light turned on. This is the correct test result and confirms that the speed 4 (HI) circuit is OK within the blower control switch.
If the blower motor passed TEST 1, TEST 2, TEST 3, and TEST 4; then you can conclude that the blower motor control switch is not defective on your 2001-2004 2.7L V6 Chrysler Sebring or Dodge Stratus.
CASE 2: The 12 Volt test light DID NOT turn on. This test result confirms that the blower motor control switch is defective and needs to be replaced.
