2012 Expedition Limited with dual automatic climate/heated/cooled seats.
Replaced the blower resistor, old one had a small melted area near a contact and on the pigtail. Replaced pigtail also. The AC works great on all settings except HIGH. When you place it on HIGH is works for about 10 seconds, then stops, after a minute or two it comes back on for about 10 seconds and stops again. The cooled seats work fine also. I ran the EATC diagnostics and received no errors.
The resistor obviously works and the blower motor obviously works. So why doesn't the bypass work for HIGH?
