How do you replace a blower motor in a 1990 Honda Civic hatchback?

Its actually really easy. Take the glove box out. There should be 4 bolts that hold it on. You will see a white container directly behind where the glove box sat. On the bottom of that container your blower motor will be mounted. There is one plug that goes to the blower motor. There are 3 screws that hold the blower motor on. Now depending on your tools you may or may not have to pull the white container off to get the blower motor out. To take the container out you will find 2 silver straps that hold it on. There will be 4 bolts between the two straps. Just unplug the wires that go to that box and the cable that controls the vent (or wire for CRX's) and the box should slide right out and you can change the motor that way.
