I have a lexus ct200h. I recently washed my car and now there is a delay in my
dashboard and air conditioning light to come on when I start the car. If I start the car two or three
times, they come on and will turn on and off while driving about two times or so
but the rest of the day is fine. Could this be an indication of an alternator
problem or a fuse/electrical problem?
What makes this problem better or worse?
This starts when I first turn the car on

Hello, I do not anticipate that this is a charging system concern like from the alternator. But if it happened after a car wash I do worry about water intrusion somewhere important causing electrical issues. Have you ever had the windshield replaced? If so, water could be leaking in from insufficient sealing and getting into circuit control modules. Something may be related to lighting. Just a guess, but when I hear of an abnormal concern, I start thinking abnormal causes.
