Air Cond on when starting problem


Diesel Xtrail will not easily start (cranks for a long time) if Air Con is turned on. Turn off and starts no problem. Either way cranks well does not seem to be labouring.
I notice that the blower cuts out when starting.
Question: should the air con disconnect when starting?
Thanks

Sounds like a battery problem. If the blower cuts out when starting then the amps draw on the battery from the starter is pulling the volts too low for the fan to continue running. This might also mean your starter is not turning fast enough to build the pressure needed for the diesel to start reliably and quickly.

I was assuming that the accessories including the blower are disconnected when starting and was wondering if the air should also be disconnected.

There is nothing I can see in the service manual which says accessories are disconnected when starting. Usually it is just that battery volts go too low due to current draw that most accessories temporarily turn off.
