WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect the 5P connector from the power transistor.
Measure the resistance between the No. 1 and. No. 4 terminals of the power transistor. It should be approximately 1.4 - 1.5 kohm.
- If the resistance is within the specifications go to step 3.
- If the resistance is not within the specifications replace the power transistor.

Connect a 1.2 - 3.4 W bulb (B) between the No. 3 and the No. 4 cavity on the 5P connector.
Reconnect the 5P connector to the power transistor.
Turn the ignition switch ON (II) and check that the blower motor runs.
- If the blower motor does not run replace the power transistor.
- If the blower motor runs replace the climate control unit.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.

• You are not confident in the next step or safety outcome.
