It is on the driver side under the washer fluid container. You have to remove the cross support bar and the washer fliud conainer and the airfilter box. It takes about a half hour to remove and replace. All bolts are metric.
i have the same problem with my 1996 buick regal . i think it could be related to the long antenna lead , coming from the top of the rear quarter panel , all of the way to the dashboard . i tried to find a "trimmer" , to adjust , on the radio , but was unsuccessful .
remove the driver side stability bar then remove the winshield wiper fluid container. plug the hole that you disconnect the hose from or wiper fluid goes everywhere. then remove battery. takes bout 15 minutes and about 3 bolts to get it done. enjoy
You will need to go to a dealership and get from them some type of code number for that year regal. Trust me i did the same thing. Let me guess you replaced a battery possibly or one of its cables? They will give you this code for no charge. I keep mine on the last page of the owners manual now
remove motor mount "dog bones" and also label/remove spark plug wires from spark plugs, remove valve cover, clean cover from debris, use light coat of oil to stick gasket, replace round rubber gaskets, replace cover, wires and "dog bones"
Front drivers side underneath the windshield washer fluid reservoir. You'll have to remove the engine brace, reservoir, and the two relays behind it to get access to it. The first time it took me just over an hour to replace, so make sure you get a premium battery.
