Front defrost not working


as always, check fuses first.
then scan this car, it will show, mode motor errors. huh?

those are damper. in the heater box.
there are 2 fail points (besides wires)
the control is bad,
or the damper is failing.
The FSM covers this 100%
or at alldata.com

what tech does is makes sure the control sends the signal
the damper (there are 3 types used on all cars)
if its damper motor , the FSM shows the damper tests.
which are unique to Toyota. and a spec, year, 2006.
the mode damper is failing.
the only question is why,
the answer is simple tests. detailed in all FSM of all cars made.

here ill look your up to see which of the 3 type class it is.

your car has a ACC brain, a/c controller, this controller runs the show.
it gets your inputs from the defrost switch and then sends signals
to the mode motor.

FSM quote

Air Vent Mode Control Servo Motor ControlWhen the mode select SW is pushed, the ECU in the A/C control assembly activates the air vent mode control servo motor.
The servo motor rotates to the position (FACE, BI-LEVEL, FOOT, FOOT/DEF, DEF) selected by using the mode select SW,
and moves the damper.
In auto mode, A/C control assembly controls the damper to move to the best position for the conditions without operating the
mode select SW.

I SAY SCAN iT
using any scan tool that suports full Toyota. full scans including
extended factory codes..
i say buy one.
here is one.
http://www.amazon.com/gp/product/B001QIUGVI/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

owning complex cars, and DIY, you need a real scan tool
or just guess.

Hv/a/control on console only comes out center dash


that is called the MODE damper
its like a door inside the heater box.
there are 3 kinds, (cable. /vacuum and motor controlled)
in a shop we find out
1: which kind then test the control to make sure the control works.
2: then make sure the mode damper works (it wont)
3: we then look and see this car has a motor and the motor is dead
3: we replace the motor and the mode damper now works.

the FSM shows the tests here, under HVAC, you can read that
any time, or login to alldata.com and read that.

if cable , you just watch the cable move. it either does or dont at each end (if fail its obvious why, right>?) jammed or broken cable.

if vacuum, you watch the servo move. if it dont , its bad or the control bad. or the damper is jammmed, i release the link and operate
the door, by hand, it works and i find the servo diaphram leaks
doing a vacuum leak down test, bingo bad servo.

or if electric motor dampers. i do the FSM tests,. no 2 cars
motors work the same, so i'm compelled to RTM read the words
and graphics in the FSM, it shows how to hot wire it and test
ALL angles. if fail the motor is DOA. get a new motor at any toy dealer.
there i have covered all cars made , all 3 systems.
ask questions.

2003 Toyota Echo heat not working. Fan, but no heat.


There is a valve on one of the heater hoses that allows heated water to flow through the heater core when you select heat. With heat selected and car warmed up check to see if both of the hoses feel warm. If not then water is not flowing through heater core and valve may need replaced or heater core is stopped up.

AC temperature


Servo motor? I disagree. Actually, there are 3 servo motors in the vehicle; an air inlet servo, an air mix servo, and an air outlet servo. None of which control the temperature.
The AC temp is controlled by a thermister in the cooler box/eveporator unit under the dash.
