Where is the battery on a 1998 Porche Carrera

SOURCE: how do i disassemble the winsheild in my car?

Unless you have done this before or have someone with you who has I would highly reccomend having a glass shop do it.Its not all that complicated but if not done correctly the new glass will leak or you could damage the roof pillar,but i will tell you how it's done.First thing is to remove the trim from around the windshield,take a putty knife or other thin flat tool and slide it under the trim from the glass side and gently pry up,the trim should start pulling free,look for where the trim overlaps itself and pull these pieces first.Next take a sharp knife and carefully slide it between the glass and the seal and start cutting the seal free,you'll need a second person one on each side lift the glass and walk towards the front of the car.Now start pulling the seal away from the sheet metal,if it wants to stick a hair dryer should make it easier.Now the fun part,you got to clean any residue from the seal off,100% of it,if you leave any residue the new seal will not seal properly and it will leak,methanal or a strong isapropyl alcohol will work well for this and leaves no residue.Prep the new glass by cleaning the sealing area with alcohol,install the new seal on the car,be careful not to touch the adhesive on the seal,the oils from your skin will foul it and cause it to not seal properly.Now the most important part,you'll need someone to help you and set of glass cups(large suction cups with handles,if you have a Harbor freight tools nearby they ussually have them in stock)they're not neccesary but will make the job easier,attach the cups or pick the glass up by the very edge,one person on each side and walk up the front of the car,line the glass up being very careful not to let the glass touch the seal,once it's lined up set the glass as evenly as possible on the seal,you have to get it right the first time,once the glass touches the seal its going to stick and pulling the glass back off will more than likely ruin the seal.Once the glass is in place use a towel to rub down each edge and fully set the seal,install the trim and your done.Hope this helps,like I said I would highly reccomned having a glass shop do the install as they have the experience and the tools to do the job.
