1. A system, comprising a computer having a processor and a memory storing instructions executable by the processor to:
obtain a first image of a target area that is exterior to a vehicle air conditioner (A/C) of a vehicle at a first time when the target area is dry;
obtain a second image of the target area after operation of the vehicle A/C at a second time after the first time;
compare the first image to the second image to determine a presence of condensate or an absence of condensate from the vehicle A/C; and
make a determination whether an A/C drip valve is malfunctioning based upon the comparison and actuate a component based on the determination.
