Heater control

Asked by Markhr6 Dec 22, 2017 at 11:38 AM about the 2011 Ford F-150 XLT 4WD

Question type: Maintenance & Repair

I started out to work with my defroster on
and as I went it sounded like the door closed
and no air came out I switched to def/floor
and the same thing ran a few seconds and
then no air although I could hear the heater
motor running I put the record. On and it
runs for 10-15 mom and shuts off any
ideas?

Most mixer doors are vacuum actuated ... look for a kinked hose under the dash or under the hood where the vacuum hose goes to the firewall
