Recently I disconnected my battery for like an hour and after that ECC temp started blinking.To have hot air I have to set it to max temp.Apparently I'm not alone in this.So many people posted having this issue after disconnectiing battery.
Don't want to do anything yet,just wait for those 40 -50 cycles ,maybe it will fix itself.
What a peak of engineering creation.You change the battery and your climate controll stop working.
Next time you change the tire and maybe your airbag will deploy on the middle of the road by itself or your car take off into the clouds or you lose yourr engine etc.
This car is like full box of surprises.
No offense to hard core Bonneville enthusiasts but sometime t'* too much every week have new issue.
Did I mention that I need TPS to be changed too.
Went bad few weeks ago.
