now the colder weathers back my vacuum wiper motor is not doing the job , any here replace theirs with an electric motor ?
Yes and I even posted a guaranteed to work (using easy to find and not expensive component parts) 4 speed intermittent wiper circuit in the Electric Bay section about a year ago using the stock looking wiper switch knob. This is one of those changes that should make things better, more consistent, definitely safer and one that to the public is invisible. I used a conversion kit (for the wiper motor) I bought on eBay...cost was about $150 or so when I bought it. You may have to bend the mounting hardware a bit to make it fit just as you wish, but this is easy. Hint: remove the speedometer and remove the radio & speaker grille/trim. This will make swapping it much easier. Another hint: the electric wiper must be mounted inside the cab on the AD truck and because the dashboard acts like a sounding board you will hear it. You can reduce the noise a bit by using rubber (at mount/screw points), but I haven't found a way to completely eliminate it. Third hint: electric wipers use wiper arms which had a bit more spring tension. Vac wipers were made using less tension because the motors didn't have as much strength. The new (reproduction) wiper arms seem to be made with the same sort of tension used in electric systems...and this may be why some people say their vacuum wipers don't work as well after changing them.
Doc, I don't know if anyone sells a rebuild kit for the AD vac wiper motors any longer. Back around 1975 I bought one and tried it, but it didn't improve things all that much. Good luck with this.
