Air conditioning stopped cooling / no response to AC button

Q: How to fix Air conditioning stopped cooling / no response to AC button in Ford ESCAPE?

The AC compressor did not want to turn on even though the relays were operational. After examining the installation, melted or burnt cable plugs ("melting pigtails") were found directly at the compressor clutch, which resulted from high current flow or corrosion as old compressors wore out. The repair consisted of cutting off the faulty connector and using an improved Ford repair kit (e.g. Motorcraft WPT-869).
