HOW TO DETECT THE SIDE MIRROR GLASS FAILURE

Sometimes it is sufficient to visually inspect the components to detect their malfunction. Cracks, chips and scratches indicate the necessity to install new components. If the mirrors are equipped with heating, a multimeter is required to check them. You need to connect its probes to the appropriate contacts of the mirror heating element, and check whether the resistance exists. If it is absent, then the circuit is open. You also have to check power wire integrity by connecting the multimeter to the connector terminals and measuring the voltage: it should be 12 V.
