[xj-s] Heater not working -- SOLVED

List,

I was having problems with my heating not working. I changed the heater
valve, for the newer plastic one, but still would not do anything, although
the blowers would work, no heat would come up.

I just replaced my battery (the DPO was using a 300 AH that did not keep the
charge anymore); putting the right one, 600AH, breathing pipe, etc (from
Halfords in the UK); and suddenly my heating has started working! I was
surprised with all the funny noises coming out of the console today, I guess
all the flaps, etc, that started moving due to higher current

I guess the message is: if your heater is not working… do you have the
right battery?
