- Buick Ownership
- 2010 Buick LaCrosse CXS
I just changed my heat a/c blower motor and the resistor (on 11/23/18) and now when I start my car the Cadillac emblem comes up on the radio screen and the screen colors are dark blue and red. It's also intermittent. If the Cadillac emblem shows it will switch to GM and then to Buick also the screen color does not change every time it shows Cadillac either. I have not yet disconnected the battery, I planned on it after work today. Is there a way to fix this without taking it to a shop?
