“The blower of the climate control does not work when the car is parked outside in the sun. As a result the car air conditioning system is impacted with the rise in temperature. When the car is parked in the garage or in shade, the blower and air conditioning system works fine. It appears that there is a short circuit as a result of high temperature which prevents the blower / air conditioner from operating. Please check if this is a safety recall issue.”
