Hey as some of you may know I am a Honda Tech. A perk of the job is I have access to all Honda TSB's through their ISIS on-line database. My problem is that I no longer have access to Acura TSB's and related service information. On Monday I should be able to access the site again once I return to work I could just use the info a little sooner. What I am looking for is an Acura TSB for a 2003 3.2 TL (might be a 2002) about the HVAC blower motor being inop. I know there is abulletin out there that pertains to replacing the subharness for the blower motor. Any help would be greatly appreciated.

I can't locate the exact bulletin you're looking for but found numerous issues with 2 things. The subharness, and the power transistor going bad.

If the subharness has melted at the motor you're probably gonna need the motor too.

Maybe this is what you're looking for:

*2. Disconnect the brown 7P connector (C202) from the main harness. Remove the YEL/BLK wire terminal from cavity 3 of connector C202. Cut off the terminal, and tape the remaining end of the wire to the harness.*

NOTE :If necessary, refer to the terminal replacement section of the appropriate ETM for how to properly remove a terminal from a connector.

*3. Disconnect the 2P blower motor connector, cut off the connector, and tape the remaining ends of the wires to the pigtail. Then tape the pigtail to the main harness.

4. Disconnect the white 5P connector from the power transistor. Remove the BLU/RED wire terminal from cavity 4 of the power transistor connector. Cut off the terminal, and tape the remaining end of the wire to the harness.

5. Take the subharness, and insert the YEL/BLK wire terminal into cavity 3 of connector C202 and insert the BLU/RED wire terminal into cavity 4 of the power transistor connector. Tape both wires to the existing harness. Route the harness so there is no tension on the blower motor connector.*

6. Reconnect connector C202 and the power transistor connector, then connect the 2P connector on the new subharness to the blower motor.

7. Verify the blower motor operates properly at all speeds.

8. Reinstall the glove box and cover.

Thank you very much! That was the exact bulletin I was thinking about. I have performed this repair in the past and both times I needed te blower motor as well. I was not aware of the bulletin about the transistor though I have seen a few bad ones. Could you post that TSB also. Your help is much appreciated.
