P0404 is a diagnostic trouble code (DTC) for "Exhaust Gas Recirculation Circuit Range/Performance". This can happen for multiple reasons and a mechanic ...
It's in the under hood fuse box. Hopefully the fuse box has a legend on it that will tell you which relay is which? Your owners manual may have this info? Some owners manuals you can look at online for free. Notice ac clutch relay in diagram.
Good Morning Gary, would love to get a little more information from you. This vehicle actually has two sensors in the exhaust that deal with Oxygen and fuel to help the engine run correctly. The one you are probably asking about is on the exhaust about 6-12 inches from the exhaust manifold. It should have 4 wires running to it and be screwed into a threaded port on the exhaust pipe. This sensor is called sensor 1.
The button is not working. It's programmed if the other functions (buttons) work. What you can do is take it apart, clean the rubber part (the buttons) with soap and warm water. Then, use a cotton swab and rubbing alcohol to clean the circuit board where the back of the buttons contact the board.

You put the starter wires back on the same way they came off. If the wiring diagram doesn't help, not sure where to go from there?

If you think the problem is a fuse or circuit breaker, I see three fuses and a circuit breaker. Use a test lite and check voltage at circuit breaker and fuses, some are hot all the time, I believe one goes hot with the key on.
get a second opinion from an accredited service shop that has experience on your vehicle
sound like the mechanics at Midas are just parts replace and see you as a sucker customer
the first thing to do is to have the oil pressure read using a mechanical gauge
that ensures that you know that the engine is running with the right oil pressure
you can test the ECM operation by using a substitute ECM that is a known good unit
run the fault codes to see in the oil pressure sensor is a problem
At this point , test the oil pressure as suggested then change the oil pressure sensor
My guess is a fuse in the fuse panel at the far passenger side of the dash,you have to open the passenger door to check it or ....is the interior light over ride switch above the rear view mirror in the correct position for interior lighting?
