Windshield Wiper Pulse Board Help

Windshield Wiper Pulse Board Help

Postby krwjlt [OP] » August 26th 2011, 12:44am

Hello,
I have been having an intermittent problem with my windshield wipers. Sometimes they work and sometimes they don't and other times they start and stop. I researched it here and found some suggestions about old and cracked soldering on the board so I checked it out. I didn't find any signs of cracked solder. I ran some sandpaper on the spade connections on the bottom right of the board and cleaned out the waterproof connection. I haven't been able to replicate the problem, so not sure if I fixed it or not.

Few questions:
1. Is there supposed to be some sort of gasket or seal between the cover and housing? Right now I don't have anything between the cover and housing and noticed that some dust and dirt made its way in.
2. Should I put some dielectric (sp?) silicone on the waterproof connection?
3. Any other things I should check regarding the problem?


Thanks
Kevin

Every time I have come across this issue it has been the cracked solder joints. If it starts acting up again I would double check for bad solder joints. They are very hard to see. In the last picture you posted. Near your thumb are some flat / spade like terminals coming through the board. The crack will be right at the top where the terminal is coming out of the mound of solder.

egress - thanks. I will check there again. Wasn't exactly sure which area to check. I focused more on the bottom right side of the board where it connects not the plug area. How about a seal or gasket? Is is supposed to have one between the cover and the housing? Kevin

Just a follow-up. I inspected the board a little closer again and am not sure if I found a small crack in the solder or not. There was a very slight difference with a little line visible in the solder, but unsure. I have yet to experience the problem again, but went ahead and picked up a new board at the auto parts store for insurance (amazed they had it in stock and only $28). The new parts did not come with a gasket but did come with hardware and the cover, so that answers that question. Thanks again.

What brand of board did you buy and where did you get it?
