Hi folks, soliciting input to check my debugging process.
I'm in the process of adding intermittent wipers to my '88 110. I've bought the intermittent wiper arm, harness, and programmable relay, and got it all wired up. The problem I'm experiencing is that, when in the intermittent wiper setting, the coil "bounces" and rapidly toggles the pass-through input; it's not staying energized, nor having clean on/off function.
It *does* sometimes stay energized and work properly, but it's maybe 1 out or 4 wipes. When it bounces, it'll reset the timing, or wipe continuously and then reset. I was thinking that maybe the new arm had some schmoo in it, but I checked it all out and it looks good. Ground looks good. I was thinking that the problem is either the parking switch or the new wiper switch.
I'm thinking that the new switch may be culprit as the wipers will park no problem when using any of the two normal settings.
Debugging thoughts? Any guesses on how best to debug before I start throwing more parts at it?
