    Do you know how to erase those codes? That needs to be your next step. You must re-read all those codes first, then erase them all (or TRY to), then see which codes are still present. Those will be your permanent fault codes. Once you've done that, I'll look up the codes still there.

    To erase, once you've re-read all of them, you press the button and hold it down for 8 seconds, then release (the LED will come back on), when the LED re-lights, hold the button down another 8 seconds. The codes (or most of them) should be cleared. Re-check the codes (1-1-1 is A-OK or there might still be one or two that won't clear. If 1-1-1, turn the ignition off, then start the car and turn the AC on to auto. If the ECC climate LEDs are off and the blower now functions, the codes are intermittant or caused by sensors being unplugged.
    If the LEDs are flashing, blower inop, there is at least one permanent code that's the cause of your problem. Let us know what code that is.

      did you try a power stage, its the square shaped component to the left of the blower moter, with two connectors. its a very common problem and the symptoms are similar.

        One needs to clear codes and diagnose those before trying a power stage (~$100). The LEDs will flash and the blower will not work when some of those codes are stored.

          850 ECC BLOWER TROUBLE - another possibiilty 850 1993

          On my 95 850 with manual climate control the blower fan became intermittent and eventually stopped working. I found that water had seeped into the power connector located right on the motor housing. This is accessible if passenger kick panel and knee bolster are removed. I cleaned this thoroughly with electronic contact cleaner and it has been working for about 4 months.
