1994LS400

I have no problem sending it out to be fixed. I was just thinking it might be more than just the display. When the car warms up after about an hour of driving, the interior power window buttons, climate control lcd, and all the other lights start to work. I am wondering if it is not an electrical problem. I thought there might be some moisture somewhere so I left the car running for about 4hours. The problem came back quickly after the car was sitting cold. Thanks.

:cries: I just purchased a 1994 LS 400. The instrument cluster is out but comes back on after about an hour or so of driving. The climate control is blacked out but comes back on after an hour or so. Does anybody have similar electrical problems? Thanks, David
