How do i get door panels off?

very carefully, grasshopper- take off the door handle and window crank- there is a special tool that will pop out the snaps without breaking them- try a butter knife, wedge it in behind the panel and move it until you feel one of the snaps- then pry it out- it should pop out- go around the perimeter and pop all of them out- accomplish this successfully and you, too, are a Car Guru!
