My wipers and interval wipers work but I currently only have one speed with the intervals. If I turn the dial the wipers will stop until I return it to the minimum position. The module clicks and it appears to be working. The car is an 86 and I'm thinking it's the actual wiper switch on the column and not the module. I'm trying to get some advice and or people's thoughts on the issue. I have had it all apart and I've been up and down all the wiring and it's all legit. I'm hoping I missed something small or maybe the switch just needs to be cleaned some where I may have missed.
