damper

  1. General
    2004 TB LS 4WD 4.2 I have an issue with the climate control and damper doors and not blowing where it should. If I pull the fuse to recalibrate the A/C will blow where it should . When I turn it to defrost it does what it is supposed and sometimes it will go back to A/C correctly sometimes...
