I am posting for my friend. He has a 99 Bonneville SE. SOmetimes everything works well. Then out of the clear blue, the car will not start and the power windows wont work at the same time. When the car is able to start, the windows work. He works on his own cars but is baffled at this point. He put in a new fuel pump and relay. Checked the wiring the best he could. Does anyone have any ideas? Can anyone help with wiring diagrams for the car?
Thanks in advance.

Start with following this procedure on ground bus cleaning in techinfo.

The fuel pump and windows share a common ground right there. Do both sides for good measure.

Thanks, We will give it a try.

In case it helps at this point.. I've been running at work all day and thought the same thing as the two dopes above you when I saw your title.

Looks like this is part or the whole problem. Terminal needed to be a whole ton. This car had been flooded over a year ago. It was still wet in there though the rugs on top are dry. Underneath the rug is rubber, so we did not know the extent. Now everything is out drying too. He ordered the wiring diagram for the car just in case.
Thanks

It appears you have found a problem.

The ground buss that you'll want to clean up is on both wiring harnesses by the front doors. There will be a rectangluar item taped on top of the loom. That is the grounding.

Another thing to check out is where your leaks may be coming from. We have many good threads about leaks.

Hey guys I noticed this thread, and wanted to know if I am having the same problem. I just drove my 98 SE for the first time, since she had a heart transplant. I noticed the drivers side window works, but the rest of the windows do not. Would this be the same thing?

No. That would likely be the master switch in the driver'* door. If NONE of them worked, that would be a likely thing to go after.

Looks like a totally different problem. Please start your own topic in Electrical.
