Heater blower faults

Postby xj40s » Wed Jan 09, 2019 6:06 pm

My 2005 x types heater is not working correctly.
Got following fault codes
B1 262 Defrost servo motor circuit failure
B1 263 Vent servo motor circuit failure
B1 239 Air flow blend door actuator - circuit failure
B1676 Battery voltage out of range.

Car had been stood for a log time before me getting it. Battery voltage is correct (at battery) I wondering if there is a single bad wire, bad connection or fuse that is causing the emblems.

Thanks

What happens if you try this Jaguar recommended reset method?

Manual Reset
A panel / stepper motor manual reset method exists and is listed below:
• Select full cooling
• Select full heating
• Back to full cooling
• Select face followed by floor
• Then select face again
• Finally select defrost
If there is any doubt, then a battery reset should be completed; wait two minutes before reconnection.

Been away on holiday so only tried your reset fix today. I have not yet checked the fault codes but it seems to have fixed everything except no air through screen vents. I have heard the motor connection to the flaps tends to come loose / slip so plant to try getting at it tomorrow.

Removed passenger footwell glovebox and was able to move flap manually, it is as if the motor is not connected to the other end.

How much room is there to access motor on drivers side, is it an easy job to remove it?
Is there a known fault that causes motor to disconnect from flap/
