Help, on holiday air con doesnt work, error code P186.5??
 

Just driving to Italy in a 2007 Chrysler Grand Voyager 2.8CRD, old shape not new facelift.

The air con was making a hissing type noise for a while now it doesnt, the fans work but just blows out normal air (i.e. like having air con switched off)
the light for the air con is still on the climate control dial, had a fiddle about and nothing makes it work.
Did the ignition on off thing and the only thing that showed was P186 . 5 which i cant find what that means at all.
However the car had a new factory fitted free of charge by chrysler as the previous one was faulty, could this be anything to do with it, and could the error code relate to that, or this?
and also apparently you can get the climate control dial to show error codes.
anyones urgent held would be much appreciated.

Kind regards

Hi,

I think that the error code:- P1865 4-5 Shift Solenoid (SS) Valve Control Circuit High Voltage

To run tests do the following:-

TO INITIATE TESTS:
† Set Blower motor ON HIGH
† Set Mode position to Panel
† Open all A/C outlets
† Set Temperature to Cold (Both slide pots if
equipped)
† Depress WASH and A/C simultaneously for 5
Seconds

NOTE: Prior to start of test, If the evaporator is
already cold, the system will fail test. To correct,
operate system with A/C OFF and the blower motor
ON high for three minutes prior to starting test.

RESULTS:
† All LED’s will turn on for 5 Seconds
† Cooldown Test is running when A/C and
RECIRC. are alternately flashing. If A/C and
RECIRC. are flashing simultaneously, Cooldown has
failed.

CALIBRATION DIAGNOSTICS AND
COOLDOWN ABORT
Test can be aborted by doing one of the following:
† Depressing Rear Window Defogger, RECIRC and
Rear Wiper buttons.
† Cycling Ignition OFF and then ON.
† Control will automatically abort after 15 minutes
from the time Calibration Diagnostics and
Cooldown was entered.
The HVAC control module will return to normal
operation or may indicate unsuccessful Calibration
Diagnostics or Cooldown test by LED’s flashing
simultaneously.
EEPROM DATA
Calibration Diagnostics, Cooldown Status and
evaporator temperature Fin Sensor values are stored
in an EEPROM memory internal to the control. The
microcomputer within the HVAC control module uses
this information:
† To determine if Cooldown needs to run
† For proper position of the Heater-A/C unit
assembly doors
ACTUATOR CALIBRATION AND
DIAGNOSTICS.

NOTE: Do not run actuators unless they are properly
mounted on the HVAC control module.
Actuator end point calibration takes approximately
60 seconds. The REAR WIPER and INTERMITTENT
LED’s will flash alternately during the test. The control
will cycle the Blend actuator(s) to the Heat stop
first then back to Cold. After the Blend actuator(s)
have been calibrated the Mode actuator will be cycled
to Defrost and then to Panel. Successful calibration
is defined as actuator travel falling within their minimum
and maximum limits.

It may be that the system justs requires re-charging.

Hope this helps

Hissing normally means it's low on gas I suspect it has now lost too much to work.

Hi all,
I have the same problem, but I do not understand how to run the tests to find the fault.
I had it regassed a few weeks ago, so its not that.
It says 'set mode position to panel' - there is no 'panel' button as far as I know.
Has anyone got any more detail on how to diagnose? Its doing my head in!!
Cheers
Paul

Also - 'depress wash'?? - I dont have a wash button apart from headlamp or windscreen washers?
