My 2004 XC90 is suddenly having electrical issues. Thank goodness it isn't in the engine. I have to believe it's all connected. Intermittently, my door locks and windows (except the driver's side decide not to work. This is particularly frustrating when I tried to put them up on the interstate as a storm was approaching. Most of the time, if I turn the engine on and off a couple times, they will reengage or reset themselves. It also happens with the lock on the fuel door. At first I thought it was a blown fuse but since they come back on I figured that wasn't it. Any thoughts on this?
