I love the older RoadTrek models but the spare parts are hard to find!

I own a 1990 RoadTrek 190 Popular. In fact, it is the 25th Anniversary Special. However, I have NOT been able to find a "Central Timer Module" Chrysler Part # 56021861AH, which control the wiper blades. Without this replacement my RV is useless to drive. Any ideas on how to find this part on this now 26 year old RoadTrek? My auto guy has tried the Chrysler supply channels, eBay, and he says he has tried "salevage yards, etc although he may not have the time to do the research that I can do. Thanks, Bill Roberts

I you can find a schematic for the wiper circuit, we may be able to come up with a way to wire it up for single speed or multiple speeds with manual switch. It can be harder to do auto park of the blades, however as that requires reversing the direction different stops.

A bit of digging would seem to indicate that this is the original p/n. The one you have may just be a supersede. I did find an application chart that showed it for 1990 B vans.

possible fit

Just for reference, this is the listing with application chart. A junk yard vehicle on the list should have that part in it.

Thank you for responding. I will see if I can up with a wiring diagram so that the Central Timer Module can be bypassed. I have looked through 9 car parts web sites, as well as eBay Motors and amazon.com so this part is just not available. What I have NOT yet done is start looking at salvage yards and auto parts recycling centers that might have a 1999 Dodge Ram Van 3500 where the part could be harvested from.

Thank you for responding. I will show this to my auto guy. The Chrysler Part # 56021861AH is the original part. Perhaps this could supersede it. I still have auto salvage yards and recycling centers to start my research.
