improper maintence and mostly poor design buy the new one from napa it will last twice that of rebuilt
Was there a 1984 Oldsmobile Cutlass Calais? I see them listed at 1988-1991. Assuming that you mean "wiper blade" (blade and frame) which are replaced often rather than "wiper arm" (piece from the spindle at the hood to the wiper blade) which are rarely ever replaced, ALL 1988-1991 Oldsmobile Cutlass Calais' have 3/16" Side Lock wiper arm attachments. See Sources and Related Links below.
They are replaced when they go bad.
The filters are what needs to be replaced most often on the air conditioning units.
Assuming that you mean "wiper blade" (blade and frame) which are replaced often rather than "wiper arm" (piece from the spindle at the hood to the wiper blade) which are rarely ever replaced, the 1991-1994 Oldsmobile Bravada has "3/16" side lock" wiper arm attachments and the 1996-2004 Oldsmobile Bravada 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. Its very easy.
I don't know about any 'free' manuals, but you can often find repair manuals at your local library. Another resource would be thrift stores and online used book sources such as Amazon.com. You might even put a want ad on a site like Craigslist. You never know what might pop up. --mark
It depends on the use, but yes, they have to be replaced periodically.
