The $5.00 Solution worth the time to read. I have had this problem more then once with my 99 Venture. The Dealer will only replace these parts as defective and give you a nice bill with a smile.

I am the original owner of a 99 Venture and have 95,000 miles on it. The wipers appear to Malfunction by leaving the wipers up after turning the wipers off. I noticed this problem after owning the vehicle the first 3-4 years.

I found problem to be that corrosion sets in between the CAMS plates that circle in an opposing fasion and does not let the wiper arms park correctly. Be very careful with this mechanism if you have the cowling off TURN the KEY and WIPERS OFF and watch your fingers so you don't get them caught.

WARNING if you leave the power on and try to move the arms This cam mechanism springs to life and will try to self park the wipers on their own so Turn the Power and Wipers Off.

SOLUTION: 1. With the ENGINE COLD, Spray a lubricant that FREE'S CORRODED PARTS like WD-40 between the gap of the 2 CAM Plates and on Top of the plates, or use some other automotive parts lubricant that free's corroded parts(let it soak for 5 minutes). 2. Gently Try to manually move the arms back and forth a little bit so that the spray works into the parts. 3. This may not be necessary but I had to do this the first time. There is a notch in the top cam that has a STUD that locks the 2 CAMs together. You can push on this STUD to unlock the cams by manually moving the wipers(use a screw driver to push on the STUD and have a friend gently move the wipers manually. Spray the area LIBERALLY with with the Lubricant Spray and see if you can move the CAMS back and forth and work the lubricant in.

Then with the wiper cover out of the way and all tools clear Try to cycle the wipers HIGH and LOW, ON and OFF a few times it may stick the first couple times with the wipers in the up position but I am confident that the lubricant will work its way in and free these CAMS the way they are supposed to. Your wipers should self park after cycling them after 5-10times. This should solve most of the problems with these wipers and should be relubricated as needed. Clean up any extra lubricant Put the wiper cover back on.

Another bright idea from GM stock holders. There is a cam for the wipers that is about $85 at your local GM dealer. It has instructions on how to install it correctly in the box the part comes from. I went through a couple of new arms ($25 ea) before a great GM parts guy told me that the cam is the one to replace. IT's worked good ever since. Good luck!

Turn the wipers off, pull the wiper arm off, and replace it in the correct down position.

If the windshield wipers work when pushing the lever down but not when they are turned on all the time, the problem could be in the wiper motor relay switch. There are two different relay switches for the windshield wipers, so that if the one fails a person can still clear the windshield manually.
