Tip & How-To about Oldsmobile Aurora
Start inside the vehicle on the drivers side, remove the drivers side bottom dashboard plastic panels, you'll need to pop out the switches on either side of the steering column to access the 10mm bolts that hold the plastic panel, and steel panel under it. Working directly in front of the console above the floor, by the firewall, will be a black plastic cover on top of another black plastic cover. They are held in by 5.5 mm screws. Once both panels are removed, you will finally see the heater core. There are 2 straps that hold the heater core in place. Remove the 5.5 mm screws that hold the straps to the housing. Now, from under the hood, around the center of the firewall, there will be a rectanglar shaped vacuum box mounted on top of a relay bracket, remove to 3 10mm nuts to move vacuum box and relay bracket out of the way to access the heater core hoses. It may help to, from the inside, push the heater core forward thru the firewall, and then from under the hood, cut the aluminum tubes a inch or so from the heater hoses, a long sharp edge flat blade screwdriver might help. You can do this from inside the car, but watch for anti freeze. Remove the hog ring clamps, vice grips might help, in removing them. Use alot of WD-40, by spraying between the hose and the tubing, use a thin screwdriver between the hose and tubing to break the seal of the rubber hose to the tubing. Remove the 2 tubing pieces from the heater hoses. You are ready to reassemble. I'd replace the clamps with some worm gear clamps, alot easier to deal with.
models there are two screws that need to be taken out, the inside latch area (plastic cap covering it) and the door pull (normally down in the bottom covered with a plastic cap), thin small flat blade will work to remove. once the is done you will need to pull out the latch area on the driver's window control panel, disconnect the connectors. set the aside, next you will need a thin flat blade screw driver or flat pry bay, start at the bottom of the door to pry out the panel, check for screws, if you cannot see any proceed to using the flat blade to remove the panel (will make a loud snapping or popping noise, this is normal) once you have loosened the panel, you will need to remove the plastic covering the access to the mirror (small triangle black plastic piece). this should now allow you to set the door panel aside, check to make sure you have removed all the clips. carefully remove the plastic lining cover the door, try not to tear or rip it. now you will need to remove the glass, there are two holes the allow access to the bolts for the window, connect your Power window switch and raise or lower till you can see them ( possibly a 10 mm socket) unscrew and set aside, hold the top of the window with one hand and lower the window to separate it form the brace. tilt the front side of the window down and remove glass set aside, replace your new window and re assemble as you have taken apart, most cases this is about two hours, Good Luck !!!
