I replaced a noisy but functioning AC blower in an '05 ES330, with a new part. I've not replaced any panels or the glove box yet. After part swap, I attached plug to blower, and reconnected the battery. Car starts as expected, and everything else works, but no function from the blower fan switch. DIsplay does show increasing bars for blower speed. I then disconnected plug from new part, and plugged in original noisy part, but no fan function with that part either. I've not replaced any panels or the glove box yet, as I wanted to verify that blower was working before I reinstalled all the panels, etc. Is there some interlock switch on a panel that is needed for the blower to function ? Or any other idea what my problem might be ? Thanks for your thoughts

Gene, Thanks for the quick response. Thankfully, it didn't get as complicated as the issues you described with the grounding wires.
But it did prompt me to re-check all the connecting plugs, and I found an sever instance of AMO - amateur mechanic oversight.
Re-seated one of the plugs, and away we go.
Thanks again.
