hello fellow cadillac forum members, ive read most of the problems on climate-controls here on the forum. but maybe someone can help me with this one.After startingmy 93Deville the climate control display is blank and its blowing 75-degree air through the defrost. this will go on for about 15min. then it comes alive and i have control again. any info is welcome.
