Unscrew inside panel on tailgate (3 screws-1 each side, 1 in the middle), unclip and remove by pulling up and out towards the rear. Unscrew all screws holding steel plate down, unclip plastic clips that hold the rod running behind the plate and unhook rod at top of that opens the window. Unclip wiring harnesses, remove wiper from the outside (1 nut holding it down)and unbolt the motor. It is pretty self explanatory once you have the steel plate removed, just remove and install the screws and clips in the same order and try it out before you put all your screws back into the steel plate since there are so many. Back window must be closed for wiper motor to work. To save yourself from replacing the motor with a new one, 9 out of 10 times it is simply the locking washer has come off of the gear inside the motor, if you pop off the plastic motor cover you will see the washer is off the gears are out of place. I realigned the gear and replaced the washer with a "C" clip and it has been working great for over a year!
The relay is attached to the bracket that holds the wiper motor to the hatch.

Very Carefully
Remove the wiring harness from the back of your 1995 Chevy Lumina front wiper motor. Remove the traveling arm linkage from the wiper motor. Remove the wiper motor retaining bolts. Reverse the process to install the new front wiper motor.
Replace the wiper motor with a NEW one (do not use a rebuilt!)
Depending on the year, the wiper motor could be under the cowling or on the firewall. The firewall motor simply unbolts and is removed after the wires and linkage are removed. The cowling motor has to have the cowling removed first, then the wires and linkage are disconnected and the motor unbolted for removal.
