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!!!

Thanks Guys! I'll check for the pressure switch, but haven't done anything with the AC (which works fine). I first noticed this a few weeks ago, when the temp gauge went past the halfway mark briefly. I turned on the AC to see if the fan would kick in, and bring the temp down. The fans came on a few seconds later, and the temp gauge went back to where it usually reads: just past 1/4. The outside temp was in the upper 90's then, and it was a blip that lasted for less than 5 minutes total.

My niece's fiancé is a mechanic, and just got a job at the local Toyota dealer. The place has SEVENTY BAYS! The customer waiting area has lounges, a cafeteria, and a small movie theater! It's been a dream of mine that he worked there instead of the local Honda dealer, and the dream has come true. He told me that they were too busy to squeeze me in, so I decided to tackle this myself. Not an easy job, unless you want you don't mind replacing things that might not need replacing.

I'll post whatever I find.......

EDIT: Batman, I found the pressure switch going into the AC line, and disconnect/connected it. Nothing changed, but it was a quick job.
