DIY: #Volvo C30 S40 V50 C70 CEM Removal and Cleaning

Video tutorial on how to remove and clean the Central Electronic Module or CEM for short on a Volvo. This particular car I am working with here is a 2007 Volvo C30 and a similar procedure can also be found on the S40, V50, and C70 models. Dirty connection on the CEM can cause quite a few problems either relating to the security system, ignition, gauges, wipers, power accessories, lighting, safety restraint system, a majority of electrical components in the car. For this car, my radio is experiencing an intermediate operation, especially on more humid days. This problem can also pop up if you’ve had a plugged sunroof drain or left a window open during a rain and water managed to get inside the car.
