The Automatic climate control in my 99 Crown Vic takes to squealing once in
It is a high pitched squeal like a sensor or smoke detector.
If you change it to another setting or adjust the fan speed it stops for a
few seconds and then starts up again.
Eventually it settles down for a while.
Any ideas before I start pulling the dash apart?
Thanks in advance
Not familiar with the Ford climate control, but many others have an
"aspirator" on the in-car temp sensor. This is a tiny fan that draws
air past the thermistor to sense cabin temp. On my old Chrysler it
would take to squealing once in a while 'till I took it out, cleaned
it, and re-lubricated the tiny little fan motor.
Thanks for the replies.
I'm going top check whatever kind of sensor that is behind the little grille
in the dash above the climate control. I suspect it is the sensor in there
that is squealing. It's to high pitched for a fan bearing, to my ears, but
I'll know soon enough. I'm not sure what kind of sensor is in there; with
a bit of luck it just needs a cleaning.
Thanks for the replies
