Question about 2007 Honda Civic 1.8
The lights on the console for the temp control are now longer working
A defogger, demister, or defroster is a system
is this the front HVAC defrost mode.
or the rear electric defogger. (heater element grid)
what temp gauge (engine>?) no car has climate controls. advanced.
external? (part of climate controls right) not a hand test tool.
my guess this is HVAC master, climate controls. are all the above.
these are complex on newer cars,
to fix such a complex device ,you need the FSM.
or at the least an account on alldata.com
check fuses. and read the FSM.
the FSM walks you through each fail and test steps.
on my car, it's a cable and a water valve, and a cable damper.
on your car is up to 3 complex, damper motors
and electronic thermostatic control and sensors.
vastly complex to mine. I can fix both but not with out the book.
what a tech does is , check power to the contoller first.
bad fuse, bad wires bad grounds, we use a DMM and measure the voltage at the controller, this is first.
then we check for loose connections.
i work the simple fails first (mil rules) this can find a simple problem
and by magic fixes the complex. (wasted effort later)
so the air temp sensor external, (real name) we work that first
i test the sensor voltage. is it spec, and right for current temp?
y/n, yes, then the controller is bad.
no? sensor bad, or power source to the sensor is bad.
that is how we fix electronic controls
1: power good.
2: inputs "
