Wiper problems of the 2003 Chevrolet S10

We own 2-2003 s-10s same year models and color. The only thing different are the motors. Both have been having the windshield wipers go out while in a heavy rainstorms and on busy interstates.

This is second vehicle of previous complaint. We have two 2003 Chevrolet s-10s where the wipers stop working during rain. In most cases during heavy rains while driving on highways and interstates. Vehicle has to be pulled over and the hood has to be raised to tap the motor to be able to continue.

When trying to use the wipers the switch refuses to operate correctly. Been replaced twice ( this happens under all three switches). When you turn it on it will not respond and does not wipe. When you use the single wipe will wipe continuall and not shut off at times. Some times when you use the fluid will not turn off unless you turn the engine off and restart the vechile. When in the first two notches for wiping will start to wipe and stop about 1/4 of the way up the windshield. In high position operates as if normal, must set it above high to get it to operate in high. Sometimes it only operates at one speed no matter the position except when in high mode. Many times will not turn on when you turn it on and when you turn it off will not turn of if working. This is the third switch that has done this to me. ? is there a recall on gm switches as I can find none and many people say they have experienced same results on other gm vehicles or heard of it occurring.

Windshield wipers stopped working. Checked all the fuses and found no problems. Windshield wipers well at times and stopped at very bad times; heavy rain times. After several days of chasing wires I found the micro soldering on the wipers computer board cracked in several places. The wire harness vibrated on it and the engine overheated it. The entire system needs a better attachment for the wire harness and some form of insulation from the engine.
