I may be able to help you with your problem if you describe the problem a little more throroughly. I'm not a mechanic but I did have an issue with my windshield wipers in my 1998 Oldsmobile Intrigue. I was driving in the snow on the highway when I saw a snow plow up ahead. I got into the left lane and proceeded to pass the snowplow. Just as I was passing the snowplow put the blade down on the ground and began plowing at about 40 mph. The snow flying off the truck struck my windshield. There was a lot of force there. Actually I have no idea how it didn't break the winsheild. Anyways after the blast of snow my left wiper stopped functioning and a couple miles later my right one gave out. By the time I had gotten home the only thing the wipers did was move up and down a few inches or so. I took my car to the garage to have my mechanic check it out. It turned out the plastic worm gear (spiral shaped gear similar in shape to a drill bit) connecting to the armature (rotating part of the windield wiper motor) had snapped in half. The snow had pushed the wipers in the opposite direction that they normally move. The fix was relatively cheap. I can't remember how much I payed but I know it was well under $500. The worm gear was the only part in need of replacement so the motor itself wasn't shot. That's a good thing because they are much more expensive to replace. If this wasn't your problem just describe it to me. I have a good understanding of how the windshield wipers work and the parts involved so I should be able to help you.
try checking the switch
There are several things that can cause your windshield wipers not to work. The most common cause is a malfunctioning windshield wiper motor.
Bad ground? Bad relay?
Windshield wipers don't work
Check fuse #8. Its the ignition fuse. If this is the problem, your gauges won't work either when you turn the key on.
When purchasing windshield wipers that work intermittently, they can be any windshield wipers that are the correct size. The ability to work intermittently is a wiring/fuse ordeal. This does not play a part in the selection of windshield wipers that you choose from.
It's your wiper modular
As I work on Boeing 747's, I can confirm they do have Windscreen Wipers.
The windshield wipers go back in forth if you now now what i mean
The 1999 Oldsmobile wiper switch can be located below the dashboard. The wiper relay switch simply plugs in and out.
