pull each fuse one at a time and check them , or use a multi tester to check them to find the bad one. if you are going to pull and visually inspect each one individually be sure to put them back in the same hole they came out of.
Tranny trouble
Sounds like your idle controll sensor, it most commonly looks like a spark plug, it plugs in to the side of the transmission, near the belle housing. But for now try a quart of lucas oil in your transmission, if that causes it to shift, then your bands are stretched, and most likely need a transmission.
Code 024 & 025 on 2003 mercury EATC
My 04 Marauder had the same issue...hot air no matter what. No noises and the airflow changes properly but I saw a video on Youtube about replacing the blend door actuator and toward the end it showed how to do a self test to get the codes. I did that and got a code of 025 which I think is the blend door actuator. In doing so, at least for now, the AC is working properly for both cold and hot. The AC system itself is fine and told to me by a local mechanic. Here's the video link: https://www.youtube.com/watch?v=_31kGBxyxy8
Door open warning on in conjunction with tire monitor fault
As they are two completely separate systems, I would think you have a door switch issue (located inside of the door latch) and a TMPS sensor issue. Your local tire shop should be able to help with the TPMS sensor. For the door switch, you can try cleaning the switch with some contact cleaner, but I have found that it usually requires replacement of the latch to solve the issue of the ajar light.
