Yes you must remove the arms, to do so, just use a standard screw driver to remove the caps covering the arm securing nuts on the arm drive shaft. The arms are secured on the shaft by splines and you should mark the arms in order to replace them in the exact position they are removed on drive spline. Lift the arms all the way up to avoid the spring tension when removing from the spline. Then you will need to remove the other panels that cover the motor and arm power shafts etc. Hint... disconnect as little as possible to accomplish the swap.

How to replace a 99 se Bonneville windshield wiper motor


Windshield wiper motors are generally easy to replace. You need to remove the windshield wipers and take off the small grill panel above the hood and under the windshield. You should see the motor in there. It simply unbolts and unplug the electrical connector and replace it with a new one.

How to take out the wiper motor


On some vehicles the wiper motor locating bolts have to be removed from the bulkhead and the motor pulled back slightly to gain a little access and wiggle room to the driven arm. You don't get much though at the best of times.

By the way, its usually the nylon cup which houses the motor arm's ball joint which wears out, and allows the armature to drop off, and not any locating bolt, so you might want to check and replace that.
If you find it any easier on your model, then remove both wiper arms, and the grill which the wiper arm spindles poke through. This on many modern cars is a black plastic piece, but on yours is metal with some grill slats punched into it I believe.
It should look something like the picture below.
Well you need to locate any screws on the bulkhead which locate this thing, remove the wiper arms and pull it off. You can also take this opportunity to clean out any dirty old gunky debris which has built up in there over the years.

2003 Chevy SuBurban The windshield wipers will not stop when turned off. How do I locat the relay and motor? 919-880-5755


It is actually a wiper control module that controls this. I have replaced many of them. It is the cover that is screwed to the wiper gear box. Remove both wiper arms. Remove the plastic cowl cover below the windshield that covers from side to side. Once inside you will see the wiper motor/transmission assy. Disconnect the electrical connector, and remove screws from cover, and replace it.

Wiper motor replacement for a 99 crown vic


I replaced the same part on a 1994 Crown Vic. There are a few bolts which go through rubber mounts on the firewall and that is how the wiper motor fits against the firewall. There is a clip on the wiper drive that must be pressed and slid off the wiper shaft. The hardest part was getting clearence between the engine and wiper motor. If I remember there was a way to turn the wiper case to clear the engine. I have asked myself why this was engineered like this? There is nothing important in the way that 3/4" of clearance could have been given for removal.

2006 Suburban, rear windshield wiper not working, can hear motor/pump trying to work but no movement.


with wiper on try to wiggle the wiper arm with your hand. if motor is stuck this will sometimes jar it loose. you may need to do this for a minute as the wiper is a delay system. also if you can move the arm thru its sweep then it is just the wiper arm loose if this is it remove cover at base and tighten nut
