You can Select Your Vehicle to check if 94841827 fits your vehicle.

Make sure that the wiper arms are in the self-parked position, the motor having been switched off In the low speed mode. Note carefully the position of the wiper arm in relation to the windshield lower reveal molding. It should be approximately two inches above the molding. Using a suitable hooked tool or a small screwdriver, pull aside the small spring tang which holds the wiper arm to the splined transmission shaft and at the same time pull the arm from the shaft. Installation is a reversal of removal but do not push the arm fully home on the shaft until the alignment of the arm has been checked. If necessary, the arm can be pulled off again and turned through one or two serrations of the shaft to correct the alignment without the necessity of pulling aside the spring tang. Finally, press the arm fully home on its shaft and then wet the windshield glass and operate the motor on low speed to ensure that the arc of travel is correct.
