Is there a circuit breaker that controls the tail lightsheadlights and the backlights in the dash of a 1999 olds silhouette?
The 1999 Oldsmobile Silhouette has the most common hook-end wiper arms. See Sources and Related Links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Locate and press the tab or button where the wiper blade is inserted into the hook of the wiper arm and pull wiper blade out of hook. You may have to rotate and flex the blade to make enough…
All of my 2002 Silhouette outside lights had small leaks when I purchased the van used. I did not notice this when I bought it but shortly after, my rear lights all went out. I had to replace the whole assembly including the covers. I have not had any problems in the 4 years since I did that. After talking to several mechanics, I understand that is very common in the Silhouettes. Hope this helps.
