Buick Century HVAC Display May Become Dim or Go Out Completely
Buick Century Problem
Visitor, 2004 Buick Century
The entire dash went to a dim light, occasionally it will go back to normal but only for 30 seconds at most. I have been told it is a wet electrical wire under the passenger seat that to have professionally fixed is $700 but the piece itself is only $59 dollars.
HVAC display went out but if I hit it the dislay would come on for a few seconds and then would fade.
How would I remove the display to see if wires are loose?
