Re: s10 RECALL wiper motor and circuts recalled march 2005!
I fixed this problem for no cost. As is noted, the solder joints break on the wiper controller board due to vibration. I had intermittent wipers on my
1998 S-10, 2.2 liter engine; it was especially bad during heavy downpours of rain, okay on sunny days with wiper fluid. I unbolted the wiper motor assembly under the hood on the fire wall and took it apart. Saw that many of the solder joints were broken near the connector end of the controller board; a tiny crack around the circle of the solder joint, on the back side of the printed-circuit-board for each electronic component effected. I realized that intermittent contact of these solder joints was the reason why I had so many oddball symptoms on my wipers. I don't remember how many solder joints were cracked. Quite a few. Also realized that the reason why the solder joints cracked was due to lack of strain relief on the connector. The connector was held in place by nothing more than the solder joints themselves; obviously doomed to break under normal motor vibration. This is obviously a design problem and should never have happend, but you know how things go. Nothing is perfect and I love my S-10. I highly recommend this vehicle for gas milage and utility. I re-soldered the solder joints...if you don't know how to solder, find someone who does, these solder joints are critical for windshield wiper operation. When I reinstalled the wiper assembly I put a tie-wrap around the connector and mounting assembly for strain relief on the connector. That way the connector is held in place by the tie-wrap, not by the solder joints which are prone to cracking under vibration and stress. Works good, lasts a long time.
