First remove plastic panel above door to the front, covers for the bolts to the mirror. Remove courtesy light lens, unscrew one screw. Pop out the switches disconnect, remove second screw(IIRC, there should be two anyway, look around if it's not where the switches are.) Then simply lift straight up and it should come off without too much effort.
Remove the power locks and windows fuse you will loose power for your windows also
remove stud locks
make sure you remove all the things screwed into the panel like the arm rest/handle and the door handle/locks and pop off the window crank if the windows are manual. there are little plastic plug like things that 'screw' into the panel. they then pop into holes in the doorframe. just pull on the bottom, work your way up, then after they are all pulled then lift up the panel, then look for things wired into the panel like the door locks and the window buttons if the windows are electric.
yes if you are just buying those doors because they are cheaper you can put you electric locks and windows in the non electric doors
As I know it is for electric windows, electric dooor locks and alarm. Might also control interior lights.
Try checking the fuses.

When removing the door panel, you need to remove all of the screws first. Then pull the door panel off. There should be screws around the edges or the door panel, and 1-2 screw on the door handle(on the inside). Then pop the door panel off, if the blazer has electric windows and locks you have to disconect them first, if it doesnt have power locks and windows, you have to take the window crank off,there should be a screw in the center of that. Unscrew the door lock and pull up. If it doesnt have them locks then you have to disconect it from inside the door panel
did you check the fuse in both the car and under the hood?
fuse bad, lost ground or relay
Door Panels Removal & Installation 1. Remove the sail panel (Front Doors Only). (Triangle looking shape near the side view mirror) 2. Remove the door panel by carefully lifting the panel upward to release the retaining clips. 3. Remove the electrical plugs that control the windows, exc. The installation is the reverse of the removal.
As both the front windows don't operate,it is unlikely to be motors,probably a separate fuse for the fronts and rears.A contact has told me that some astra-g convertables have a central window switch which lowers all four together,you may have a wire loose on this.Also,the front windows get a signal from the central locking,if locks or battery have been disconnected recently,you may need them reprogramming at a vauxhall dealer.
