back to my heater S60 2006

Hi All
This carries over from my previous post about my heater staying on , on the rhs only
i have been busy and unable to address the issue
it is my sons car which i drove yesterday and noticed that now both sides stay on boiling hot irrespective of a/c on/off and vents open or close( i assume the floor flaps must be open)
i also noticed that the clock has disappeared again despite having only been reset last week ( dim going south i thought ). the tacho needle remains steady though
Could these issues be connected
and i read your suggestion Klaus to another member re his battery
which is interesting because the battery in this car is not the best
11.2 volts iirc and it turns over slowly when cranked but i havent checked the cranking voltage yet
so could the battery condition be the cause of my issues or any other suggestion welcomed

Thanks for listening
David

    Hi Klaus
    Well i drove the car again yesterday and i will be danged if i dont get cold air ( tis winter here ) through all the vents
    Have you known the hvac to change like this
    Do you think the climate control needs work(obvious i know )
    The young fella lost his licence for 3 months so this may be an appropriate time to send the module to the US for repairs
    Costly whichever way you look at it
    Cheers David

      Before you rip it out and send it off...

      Is the climate control on 'auto' and temps set to a reasonable temperature.

      Have you tried to vacuum out the dirt and dust from the sensor? That small grill above the right hand side temp selector.

      If you only get cold air, is the engine coolant temperature gauge in the normal range?

      Did you replace the battery? Attach a battery 'minder' to keep the voltage above 12.5V?

      The climate control module may need only to be 'reprogrammed'. A mechanic with a VIDA/DICE may be able to retrieve codes, if any are present.

    I would swap the battery if it can't hold 12V. That might clean up the DIM errors, not so sure about the HVAC.
