I have a 2000 Ford Explorer fully loaded. It has the Climate control system, and when I turn on the heat using the AUTOMATIC button, instead of like, the FLOOR button, there is a fairly loud hum noise, and the electric system seems to bog down. If I hit the FLOOR button, it stops. This all while I have the temp set at 90 degrees. Seems to only occur when hitting the AUTOMATIC button.
the sound is kind of a low hum. Almost like a soft noise a car horn would make if the battery was about dead.
Let me know what you think or if you need more info.
