Hi, My Heater vent switch on the control panel is not working. The
blower and temperature switches work fine but I am unable to get heated
air off the floor. I checked for vacuum lines and there isn't any. It
appears everything is electrical. I have tested all fuses (under dash
and hood) and found them to be working. I have checked the cables for
power going into the heater control module and that is also OK. I'm not
sure what else to do. The heat does not hit the windshield so it gets
all foggy when it's cold.
Any help is appreciated.
you have a control regulator under the dash......
get up under the dash it should be on the right side of the steering
colum...youll see hvac vent box with a gear type mec. on it turn your
switch on your vent control....at the same time look at the regulator if
it moves or not..if it moves you may need to replace or it mat just need
recalibrated..if it dont move you need to check the voltage ging to it
at setting change to make sure it isnt your control head....but ill bet
its the regulator....
