2004 Sonata heater/a.c. control panel

My heater/air conditioner blower motor ceased operation suddenly and
completely last December. My non-dealer mechanic replaced a relay,
and a resistor with new OEM parts and also the dashboard control panel
with a used one.

All went well for three months then the switch for the blower became
flaky. Only one or two speeds would work. The mechanic replaced the
control panel and that one is now showing symptoms similar to the
first replacement.

A new panel is $375 and repair parts are not sold. I am wondering if
anyone has had simiar experiences. I am concerned that a $375 new one
would only last a short time due to some other possible problem not
yet identified.

Any thoughts will be much appeciated.

If you're sure the problem is in the control head, there's little
external that would cause it to fail. If you do not have automatic
climate control, it's not true that components are not available
separately. Some (such as the blower switch) but not all, are
available separately.

If you're not sure that the control head is the issue-- we have very
few problems with these, by the way-- then I'm going to ask you to
list the exact symptoms you currently have so I don't lead you in the
wrong direction.
