Car was just detailed inside and out...when I picked up the car the A/C Rest light was on and when I pressed it again the light just blinked. There is no A/C and I had great A/C the day before.

At morning time it gives cool air but in the afternoon it changes into warm air. I took it to the dealership and they checked and said every thing is OK, but it is not. Please help!

Noticed this a few days ago... After sitting overnight, I got in and turned the key... Everything lit up fine (dash, display, etc.) but the car didn't make a sound. Turned it off and back on ...

My dealer has recommended that the fuel filter in the tank be replaced. Is this necessary? I was under the impression that those filters are permanent.
