An important component that is involved in the regulation of the temperature of a motor vehicle is the climate control module. The climate control module, sometimes described as the air conditioning system, controls the operation of the vehicle’s HVAC system (heating, ventilation and air conditioning). The aim of the climate control module is to provide a comfortable environment within the car for the driver and passengers by creating a comfortable temperature and providing good indoor air quality.

Like all car parts, the climate control module may begin to show signs of wear and tear over the years. Possible indications that it is no longer working efficiently are a failure to heat and/or cool the vehicle effectively, a failure to distribute air around the car as required and a total failure to switch on. In the latter case it may be wise to check whether the cause is a blown fuse. If the fuse has blown it should be replaced. If it blows again, the cause of the problem is likely to be a short circuit in the wiring of the climate control module.

If the problems with the climate control module are such that it is no longer possible to drive the vehicle without substantial discomfort it will be necessary to repair it or find a replacement part.
