A/C Sunload Sensor

The A/C sunload sensor (19E663):

• is located on the top RH side of the instrument panel (04320) above the glove compartment (06010).
• contains a photovoltaic diode that is sensitive to light.
• has some unspecified resistance across the terminals depending upon the amount of light reaching the photovoltaic diode; therefore the only test that can be performed is for an internal short circuit.
