I have noticed that while cruising down the highway, flat stretch, cruise set at 72, that my ac light will flash off and on. I dont notice any difference in the performance of the ac. Just dont think this is normal. The xk will be out of warranty in about 2k miles, so if its an ac issue, i definitely want it looked at before it runs out. Any body else have this issue?
You have the vent selector set to Auto, it will automatically 'turn on' the A/C for you. You only would need to be concerned if you set the dialer to a different setting (to the face, feet, windshield defrost, etc.)... then, you should see it turn on OR off, not both. I was stumped at first, but finally figured it out.
I dont have auto a/c. I run it on vent, not recirc, usually about 1/2 way between cold/warm. But i keep the a/c button on for the nice humid mornings we have down here to keep the moisture out of the air.
But....
It does the same thing when it is on recirc, so it kinda has me stumped too.
Hope that helps. It could be a faulty bulb. Just a guess.
