Where is it wiper motor in 98 buick regal and can i change by myself this one?

Since I have had 3,8 motors in a number of Buicks over the last twenty years I myself like the 3.8 motors. Never had any problem with any engines. Some were high milage .

Make sure wiper arms are tight they are on a spline also where the wiper arm transmissin conects to the wiper motor therw is a nut that holds a z shaped bracket that losens up and oblongs the rectangular slot so the wipers stop with the least resistance.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/craig_a14a43e01fd0835a

replace wiper motor the seal on motor is bad water entered and shorted at motor then dried.honda had a recall for same problem.

You need to replace the crank arm that is attached to the wiper motor. Then bend the tab back up on the wiper motor bracket that got bent when the crank arm went bad. The crank arm catches the tab when you shut the wipers off so they back up and go down to the park position.

Your wiper motor is usually against the firewall(metal wall between the engine and drivers compartment). It will be on the drivers side or towards the middle. It's black rectangular box just under the cowl( top of the firewall that meets the hood). It will have 3 or 4 screws or bolts holding it in place. If you remove it, be careful. the wiper rod is connected to it on the back side. hope this helps

apparently, something inside the wiper motor spun and now it thinks the down position is the up position.

a new wiper motor is my only suggestion since the sensors/controls in these motors arent user serviceable.

Good luck and be careful!

This is most likely the result of a bent park tab on the wiper motor bracket. To repair this install a new wiper motor crank arm (#12494832) and a wiper motor bracket service kit (#88958149). This is a common problem among many 2002 Buick Regals and Centurys.

remove cowling under hood to expose wiper motor linkage. You have to try it many times but the linkage may not be attached in the correct arc position. Trial by error.

Does the wiper still make noise like it is trying to go? If so open the cap where is attached and tighten the nut on the wiper. If does not make noise you will need a wiper motor.

im sorry but it can not be fix you need to change the window regulator if you need assitanse for that it would be my pleasure to help you thanks pierre
