How Long Does an AC Control Module Last?

Over the past decade, vehicles have become far more electronic than they are mechanical, with numerous computers on board that control various functions. Your AC control module is one such computer, and it works to manage the air conditioning and heating system in your car. Depending on the type of car you own, and the features that it offers, this could include automatic climate control – your car actually senses the temperature inside and outside the vehicle, and adjusts the interior climate for optimum comfort. With this sort of system, you set the temperature that makes you most comfortable, and the AC control module delivers it. If the module malfunctions, you will not enjoy your chosen temperature.

Usually, your AC control module will operate problem-free, and should last you the life of your car. However, like all electronic modules, the AC control module may very occasionally malfunction, or possibly require a software update.

Signs that your AC control module needs to be replaced, or possibly analyzed to determine if a software update is in order, include:

  • Temperature does not remain steady
  • No cool air

If either of these symptoms occur, you should have the AC control module checked to determine if there are any trouble codes, and then repair or replace it accordingly. A mechanic can determine whether the module can be repaired. If necessary, we can replace the AC control module.
