A cautionary tale. Ordered a genuine blower motor.
Part number JNB000060

My local independent could not make it fit properly so a second was ordered.
Same fitting problem.
My local independent told me the replacement was physically bigger than the original part, hence the reason why it would not fit.

Then I heard I was not the only person that recently had had a problem with replacement blower motors.
JLR will be asked to check the stock, and compare the new to old.

Will keep forum updated.
