Few weeks ago changed battery and got flashing lights on a/c and wiper conrols.
Done a/c calib several times
as below:
Alternative #1 (by Jerry Rogich)With engine on set blower motor to high, set mode position knob to panel (i.e. full left), open all A/C outlets, set temperature to cold (both levers if so equipped). Now press the wash and rear wiper buttons on the A/C panel simultaneously for 5 seconds (until all LED's light). This should get the test started. Assorted lights on this panel will flash as different tests are run. Eventually if the tests are passed the rear wiper LED should be the only light flashing. Push the rear wiper button to exit test mode and you should be home free.
And here a/c and recirc led's START AGAIN flash simultaneously
Codes -LEDs Problem Corrective Action
None flashing Normal None
rear wiper and intermittent LEDs flash simultaneously failed calibration diagnostics run Calibration test
a/c and recirc led's flash simultaneously failed cooldown corrective action run cooldown test
rear wiper and intermittent led's are flashing simultaneously And recirc led's are flashing simultaneously failed calibration, diagnostics and failed cooldown test run calibration test
0 = passed all tests
1= mode actuator did not reach defrost position
2= mode actuator did not reach panel position
3= blead/pass. Actuator did not reach cold stop
4= blead pass. Actuator did not reach heat stop
5= evaporator temperature fin sensor open
6= evaporator temperature fin sensor shorted
7= driver actuator did not reach cold stop
8= zone/driver actuatoer did not reach heat stop
9= control head internal failure
How to read codes above and what next?:ask_wsign
What is reason for a/c and recirc led's simultaneously flashing and failed cooldown test?:help_wsig
