On vehicles with intermittent windshield wipers, the wiper motor circuit board may fail and cause the wipers to stop working at times. Replacing the circuit board should resolve the issue. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

Wipers would not park at bottom. Also, sporadic issues with wipers starting and stopping. Bought a new control board/module from local auto parts store and installed in less than 30 minutes. No problems since. Easy DIY job.

Wipers will work for a good hunk of time and then not work correctly for a good hunk of time. Have re-soldered connections and they work for a while, then back to working/not working. Think issue is that there is too much torque on the wiper motor and it tears apart the solder joints. Will check into a new control board. This issue may also be connected to the turn signal arm issue that I have read about all over the place. Retightening the wire harness from turn signal arm that is hooked up to the firewall helps too, but again temporary.

Just bought the car from my girlfriend's coworker a week ago. I found out the hard way when it rained that my wipers don't work. I have the same problem and I see the part at O'Reilly's website for $35. I'll see if I can get my girlfriend's stepdad to help me fix it up.

Not fixed, now has 170k. Don't know how to solder myself and new board cost $70. I just live with it, but it is dangerous to drive when I cannot see in the rain. Never got a recall notice. Wish it was fixed as I like my Blazer. Same thing happened to our 1990 1/2T pickup so the problem with circuit boards never corrected.

Front Wipers work when car cold in morning for about 10 minutes or single wipes for about 20 minutes. Once warm, nothing. Rear always seem to work. Will try the thread that points to a cold solder or solder failure.
