MANUAL A/C DIAGNOSIS TSB Revision HEATER, AIR CONDITIONING AND VENTILATION 55A-143 STEP 4. Check the blower relay continuity. Follow the table below to check the blower relay for continuity. Q: Is the blower relay continuity in good condition? YES : Go to Step 5. operate normally. STEP 5. Measure the voltage at blower relay connector (1) Disconnect blower relay connector C-202, and measure the 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.
