I have a 2006 Chevy Tahoe that I have had for a year or so. I pulled it in my garage to put replacement rocker panels in.i put it on ramps on one side to make it easier for myself. I put the drivers side in Welded it pulled it off the ramps to put the ramps on the other side. I just got it done. Went smooth. When I got it completely done I went to pull it off the ramps it would start but for only a split second before shutting off. Now I’ve heard horror stories about people frying computers while welding if you didn’t take the ground off the battery. So I made sure to do that each time I welded. Also with the key on my windows don’t work. And as soon as you plug the battery back up the radio is always on no matter the key position. I would really appreciate some help on this one. Also I have checked all fuses.
