This module for cooled/heated seats is this one also listed for a 2020 Edge Titanium.  https://ford.oempartsonline.com/oem-parts/ford-seat-heater-control-module-bu5z14c724a  

If service mode is actually activated, that means the electronic parking brake actuator is not engaged, you just need to compress the pistons in, like with that same C clamp you used on the front. Only time you might need to rotate it clockwise (either side, same direction) is if it won't compress enough to be fully compressed/you can't install the caliper with new pads over a new rotor.

Yes, that module is under the driver's seat but I believe that is only for the seat memory functions. Anyhow, all six of the connections are good.   It's scheduled to go in the shop next week and I'll let you guys know what it is.   Thanks for everyone's help! 

Good info and makes perfect sense

Not sure if you have done this or not:   Have you looked at the Ford Parts diagrams for your 2020 Edge to see if you can find all the related parts & part numbers for your driver's seat?   That's where I would have started first when trying to locate a particular part.  Unfortunately not everything gets individually listed or listed at all but it's a good starting point.   https://ford.oempartsonline.com/oem-parts/ford-module-gu5z14c708bp This is for heated and cooled seats and may be your issue.

So, I just ordered another tool but I learned that some pistons (rear with electric parking) are right hand threaded and some are left hand threaded.  Anyone know which it is for a 2015 SEL?   I don't want to crank on it in the wrong direction.   Thanks. -D

So, those of you who have done the rear brakes ... what tool did you use for the electric parking brake calipers?   Used the C clamp on the fronts.   Put car in brake service mode, removed the caliper ... but the cheap tool I bought to screw in the brake piston would not budge the piston.   Thinking I need to rent a tool?    What did you guys do?  

Just adding this follow up in case anyone comes across same problem. Doubtful but just in case.   I went to a couple of salvage yards to look at other edges of the same year. none of them had cowl drain hoses. So this must be the standard for this year model.    The issue was the seams highlighted in the pic.    I guess the the sealant broke down and stopped working after almost 20 years. I applied fresh caulking which fixed the rain leak.   I have added 2 pics below. One is of the cowl basin that is closest to the driver side bay. If a pool of water stays in that part then it will leak through the seal that is highlighted. The water ends up in the cabin.   The 2nd pic is view under the cowl before I applied the caulking. The water also leaked into the cabin.   No more water wet carpet! Just in time for the rainy season in PNW.

Thanks for the info.😊

Okay it turns out the module under my driver's seat is the for the seat memory. I found no TED's module under the passenger seat. Any other ideas as to where I should look?
