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.

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.
