About one month & half I replaced the A/C compressor since the original one leaked out all the oil and quit. I installed a remanufactured one with no problems of course including the drier. The system was not contaminated. Everything was fine the A/C worked perfect until yesterday. After making a stop at the store I get back in the car when I go to turn on the A/C nothing happened. The blower did not turn on at any speed, auto or manual and I did not hear the compressor either. After I get home I open the hood I go back to the car try again, this time the Compressor kicks in but the blower does not. Today I kept troubleshooting, checked all fuses they are good. This time the compressor starts for 3 seconds and stops. I think I may have a bad relay. But what are the chances of both relays (Blower & A/C Clutch) going bad at the same time?? maybe they share the same circuit. Any thoughts before I take it to the shop. Thank you very much.

There is a TSB on your vehicle, posted here. Hope it helps. SYMPTOM The blower motor does not work at all. PROBABLE CAUSE Poor connection at the blower motor caused by tension on the wiring harness. CORRECTIVE ACTION Install a blower motor sub harness. PARTS INFORMATION Blower Motor Subharness: P/N 04321-S0K-A00 REPAIR PROCEDURE 1. Remove the glove box and cover: ^ 199~03 3.2 TL: See page 20-66 of the 1999-03 3.2 TL Service Manual. ^ 2001-033.2 CL: See page 20-64 of the 2001-03 3.2 CL Service Manual. ^ Online, enter keyword GLOVE, and select Glove Box Removal/Installation from the list. *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.

Thanks Thechnoiceparts, But for what I saw in my existing harness that TSB has already been done. I do get voltage at my blower connector. What bogles my mind is why does my compressor doesn't come on either. The first time I noticed the problem the compressor was working now is not. How about the blower transistor? How do I test?

For anybody reading this thread with the same problem. I found the problem and it wasn't the TSB, the TSB had already been done before. The connector at the blower connection had partially melted down and was partially burned. This was problaby caused by 10 years of vibration and bad design. To correct this I'am replacing the blower, since the blower's connector's male which partially melted is part of the blower's housing.A local trip to the junk yard will provide me with a female connector. Just make sure you solder the wires connections using (heat shrink). Or use a goog crimp connection!! Good Luck!
