Both Fans Run All the Time...Solution Question, 5SFE Options

[FrankB2]

Hi Guys.
Both of my 1997 2.2 5SFE fans run constantly, even after turning the ignition to "On" in the morning, but not starting the engine. A quick search here suggests the problem is the Engine Coolant Temperature Switch, located at the bottom rear of the radiator. Before draining my coolant, I thought that if this is the problem, disconnecting the wire from old and connecting it to the new without installing it into the radiator should keep the fans off with a cold engine (or just turning the ignition to ON without starting a cold engine). Does that sound about right to anyone? Also, does this look like the right part:

TIA!!!

Hi Smaay,
It seemed weird that the idle was dropping with the AC, so I did a search here that led to an Autozone idle up valve check and diagram. I went out to the car, and it was still around 400rpm in drive with the AC on, so I disconnected the power to the idle up valve, and reconnected it. INSTANT FIX! Now it runs just a hair above 1000 rpm with AC on in neutral, and 750 rpm in drive. Took it out for a test ride, put it through the paces, and all is well. Both fans still run all the time, but my idle is sweet again.
