About a 94 Buick. About 2 months ago I installed a new windshield washer motor, it worked fine. Today it quit working again.Would I do any damage by putting 12 volt power from a portable battery direct to the pump motor,just to see if the pump is shot again ?
You dont need a portable battery. put a fuseable link in a wire n hook it up. you may not even need the fuse but its a good idea
