94’ HH3 having power steering issues. I got the van recently and have the center link pulled to replace the bushing that seems to be common on these. So I went ahead and pulled the rack to clean and grease it. An issue I had noticed before and thought was rack or bushing related has shown to be in the upper column. Upon pulling the cover, I’ve found that there is some sort of electric power steering assist. That appears to be causing the issue. (Issue being choppiness or notched feeling when turning the steering wheel) I can’t find a fuse for it, or any information online about it. I have done a forum search as well. I’m hoping that someone here can give me more info on that system and/or issues with the system, or possible fixes. Thank you in advance for any help.
