Having just returned to Colorado after 5 years in Phoenix I suspect a
problem with my heater controls. The DEFROST setting seems to work
barely sufficiently, though I suspect not as strong airflow as it
should, I don't get much out the side window defrost outlets. Both the
ECON and BI-LEVEL settings give identically poor airflow at the
defroster and footwell outlets and barely noticeable airflow at the side
dash vents. The AUTO setting while calling for heat also gives the same
result. The AUTO setting when calling for A/C works fine giving most of
it's airflow out the center dash vent. I recall that I used to get
pretty strong airflow at the side dash vents with the ECON setting and
calling for heat. It seems as though there is a blockage of some sort
restricting airflow when calling for heat.
I had the blower and heater core replaced about 18-24 months ago. None
of these problems coincided with those repairs as far as I know. One
other perhaps useful tidbit, the part of the climate control that
controls fan speed hasn't worked right for years. I just use the HI and
LOW buttons to control comfort. One other recent development, when in
A/C mode an air control flap will close off the flow to the center dash
vent for a minute or two whenever it feels like it
Also, my seat heater just stopped working. For a long time it
functioned fully "on" regardless of what the control was set to. And I
could hear a "clicking" sound occasionally after awhile but not always.
Sounded like a relay clicking. Do you think the fix is as simple as a
relay if there is one?
I suspect I don't have exclusive rights to these symptoms and hope that
someone can help me cut to the chase, thanks in advance for any advice.
