YES : Go to Step 5. operate normally. STEP 5. Measure the voltage at blower relay connector voltage at the junction block side. (2) Turn the ignition switch to the "ON" position. (3) Measure the voltage between terminal 1 and ground. • The measured value should be approximately 12 volts (battery positive voltage). Q: Is the measured voltage approx. 12 volts? YES : Go to Step 7.
