Why is there a vibration when I turn on my ac? on 2002 Toyota Camry

I had a slight fender bender several years ago with no major body damage. Ever since then when I turn on my ac there is a vibration. Sometimes even when I am sitting at a stop light the fan will seem like it is vibrating. This happens all the time.

check the motor mounts. you may have a worn mount causing this.

Or mis-aligned from collision work.
HAVE BLOWER CHECKED FOR FOREIGN OBJECT IN CAGE FAN. IF YOU TURN OFF
AC BUT LEAVE BLOWER FAN ON HI DOES THE VIBE. GO AWAY? IF SO COULD
BE IDLE CONTROL PROBLEM. IDLE SPEED TO LOW. I OWN ONE JUST LIKE IT!
AND THAT WAS MY PROBLEM, LOW IDLE, YOUR MECHANIC CAN TELL YOU.
GOOD LUCK.
