Heat blows cold air
The LH models (LHS, Concorde, New Yorker, Intrepid, Vision) do have
self-diagnostic capability with the standard type heater controls. I
don't know about the Sebring heater controls (my '95 manual doesn't
mention it) but if you have the various controlknobs/buttons that I will
describe you could give it a try.
There is a rear window defogger that is initiated by a push button with
an LED light. That light is the readout, by its blinking. To begin the
diagnostic mode, run the vehicle at idle with the controls set as
follows: the blower speed knob should be on any position other than OFF,
the temperature knob should be set in full COOL, and the mode knob
should be set on Defrost mode.
To enter the diagnostic mode, press the defogger switch in for five
seconds, until it begins to blink, then release it. It will continue to
blink for about 30 seconds while it calibrates. If it goes out, the
calibration is OK and you can skip 3 paragraphs to "Position...mix mode"
If the light stayed on, switch the mode knob to the MIX
(defroster-floor) position. If the light stays on there is a problem
with the control head unit.
Switch the mode knob to the FLOOR position, if the light stays on, it
indicates a problem in the blend door or the blend door actuator wiring.
Move the knob to the Bi-level (panel-floor) position where a continuous light indicates a problem with mode actuator or circuit.
Position the knob in the MIX mode. The LED light should now flash twice
then pause, and continue a two-flash sequence, indicating that the MIX
mode is OK.
In the FLOOR mode the light should flash three times, meaning that the FLOOR mode is OK.
In the Bi-Level Mode, a four-flash sequence indicates that mode is OK.
In the PANEL mode the light should flash 5 times to indicate no problems
there, and in the recirc-panel mode 6 times and seven times in the
recirc Bi-level mode.
The temperature control can be checked by switching the mode knob to
Defrost and rotating the temperture knob. If the temperature contol is
OK, the light will flash faster the more you turn the temperature knob
up, until the light goes out at the hottest setting.
Switch the knob between Panel and Recirc-Panel and watch the recirc door
(unit under the dash). Proper operation means that circuit and
components are OK.
To get out of the self-diagnostic mode, turn off the blower or push the air conditioning button once.
If this doesn't seem to apply to your control head or you get no
response from an LED light for the rear defroster, then the Sebring may
not have this capability. Please let me know your results if any
