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.
A/C REST LIGHT BLINKING on 2005 Mercedes-Benz E500 4MATIC
Possibly the detail shop sprayed something where it should not have been sprayed or they may have bumped the outside ambient temp sensor for the A/C and knocked it loose, which will shut down the system. This can happen in a car wash.
