20191130_wiper Motor Trans Fluid

Old trick i've seen on several videos. Take the vacum lead from the wipers, run it to a cap filled with transmission fluid, and manually move the wipers. What this does is sucks up some of the fluid into the internals, this softens the old leathers and rubbers inside and restores the movement, mostly of the wipers. Not sure of the long term of this lubrication, might be more solvent like...but it worked for me...the wipers worked again!
