Windshield Wiper Fix

This sounds funny, The board is conformal coated, usually a pinkish red color. That should keep the grease form interfering. There are contacts on the back side of the board that tells the controller where the wiper is. Also, moving the connector around will and can make it look like the problem has been fixed. The hair line cracks are very easy to miss.

Best repair to do, with out a replacement, is to clean the solder from the connector pins. Bend the pins onto the circuit board lands. Then resolder.

AJ, Not 100% sure about the Blazer but think you will only have to remove the 3 screws. I believe mine has 4, but removing 3 of them takes it off..

The wipers on my 95 Silverado work fine but when I turn them off the wipers bounce back up 2 or 3 inches from the bottom of the windsheild where they should stop.Is this problem related to problems with the circuit board as well???

Thanks.. Earl

Your wipers will likely screw up again. You most likely just moved the plug around making the connection on the bad solder joints. Just for info, you can remove the cover and the board without removing the whole thing on most trucks to re-solder the bad joints on the plug.

I would definately take the cover off and have a look at the circuit board. Wipe off all the excess grease and check the solder points....
