Pour warm water were it shuts. Also, if can reach the car with an extension cord you can use a hair dryer.
If the door is shut then it's probably the switch in that door or wiring to it.
Do NOT pour hot water on a frozen car door, your window will definitely not make it! Cold window in frozen car door+hot water=broken window. Try taking your ice scraper and actually prying the door along the seal to get it to pop open.
Get a new car you loser.
Put luke-warm water on it. Boiling water will crack glass.
remove door card,remove door rubber and interior arch trim panel,unclip lower seat base,this should give you access to the latch mechanism on the door shut,now have someone outside of car hold door handle in open position whilst they apply pressure to door (as if pushing shut) now simply lever locking latch up with a screwdriver or similar until it is clear of the door shut lock post and in open position

rear washer spills water. check it first.

a door in your car is not fully shut.
Try checking the latching assembly on the door. If it snaps shut before the door colses, it keeps the door from closing. With the door open, look at the assembly while pulling the door handle to open. Use a screw driver and snap the latch that holds the door shut down. It should pop back and reset. Worn out door hinge pins and bushings lead to poor alignment and damage to latch and striker pin.
sounds like a bad door latch mechanism.
