I have a '94 Astro van with intermittent wipers that freeze up when in use,and won't return to stop position.Is the module gone and if so can you replace it easily,or must the whole wiper motor assemlbly be changed?


Hi, my name is Tim West.

Hi, my name is Tim West. Chevrolet is known for this issue. I think the part you are looking for is called a "pulse board". It will set you back about 30$. You can buy this at the everyday parts stores. (Autozone, Napa, ..) To make the repair is very simple, get the board and you will see what I mean, let me know if you need any help. The labor time on this fix is a .2. A tire rotation is more.
