Funny story. I bought a Jeep with a non functioning wiper pulse board. After 30 seconds of Google searching, I found this thread. I popped the non-functioning board open and voila. Exact same trace in the exact same location was burned out.
Many thanks to the original poster! Turned the wipers on a month ago with snow blocking them, and intermittents stopped working. Terrible as I am with solder, fixed it in about 20 minutes. One hint that worked welll for me: I used the tip of the iron to burn off the green coating on either side of the connection, revealing bright copper. Solder stuck like a champ, and even with me sliding it around to make the connection, it worked perfectly on install.
My delay function hasn't worked since purchase, and just this week the whole operation went out (front wipers/washer doesn't work at all). I figure that, because the washer AND the wipers don't work, it is most likely electrical. If the washer still sprayed water, I'd check out the wiper motor.
My question is: does the pulse module control all functions of the wipers or just the delay? I know that if it works on HI and LOW but not in between, it's most likely the module, but if it started that way and now doesn't work at all, could I just have two problems (the module and control switch).
I have this same problem on my wifes 95. I have been searching since i found this thread for a new module and it appears to have been discontinued. only wanted to have a new one sourced just in case i fubar on the repair. if any one knows of a source for new modules let me know please. TIA
