1997 Ford F150 V8 Two Wheel Drive Automatic 112, 00 miles
I have no control of the heating/cooling temperature on my 1997 f-150 with 112, 00 miles. Both the air conditioner and heater work fine, but it appears that the blend door changes position randomly. When the system is operating I can hear what I believe is the blend door popping open or closed, followed by a change from cold to hot air or vise versa.
