Can someone explain to me why my air conditioner in my 2004 350Z automatically turns on when I am driving around? It just kicks on randomly? I am not driving the car hard, and it is not over heating by any means. Not a huge deal, but annoying. Any way to prevent this?

Thanks for any ideas....

I've had that issue ever since I bought my car in 05 so you're not the only one. Maybe a ground issue? Or possibly kinked/damaged harness behind the AC dials.

Thanks! Glad I am not alone!...It's weird - it seems to kick on when the weather is cooler. No problems on hot days or if I am getting my last run in around November before I store her. Today the temps are in the mid 70's and very pleasant. Open windows and flying down country roads and on comes the air!?!?

I had this happen to me...when it happens push/put some pressure on the area where the AC controls are. the trim not the button. If it turns off, then you likely have a loose connection in the back/inside. I think it is the white ribbon cable connected to the AC controls.

with the whole system turned off or is this with it on auto mode?

I'm experiencing the same AC Ghost on my 2003. I will follow JV350z's recommendation and post the results.

I've never had this problem in the z but I have had a similar issue in my Jeep, I replaced the AC & heater control unit and that solved the problem.

I followed the recommendation provided by JV350Z. I pushed on the trim next to the AC/AUTO switch and the unit did turn on. After doing this the AC ghost has gone away. I will see what happens over the next week or two to see if the ghost returns. If it returns I will look into doing a visual inspection of the wiring and AC Auto switch.
