No other suggestions from me. I am betting that it's the transistor, which I guess you have read can be fixed for a few cents without replacing the entire assembly? Good luck.
I bought one on Amazon for $21 which comes tomorrow.Mr Wiles, I hope you're well and still have an interest in these Odysseys. Our 2001EX A/C has suddenly stopped blowing cold, and stopped blowing at all except for intermittent high fan speeds. The control on dash feels like it's not connected to anything. I realize we may need a clutch or compressor but it seems that the blower resistor near the blower motor under glove box may have stopped working. Do you have the EX part number? I see 2 different inexpensive parts on ebay for this; one has three different size blades and one has only one.
