69 c10 wiper function problem

[pbzzz]

I had the cowl cover and wiper arms off of my truck for 2 months . The cab top was being repainted and he also did some paint/paint brush work down in the bottom of the cowl area where the wiper motor and control arms are . Upon putting it all back together today I have the wipers going left to right to left properly while they are ON . . . When I turn the wipers off the arms / blades stop in the up / far left (looking out) position instead of down ( to the right) .
This is consistent .

I have had the cowl / wiper arms off several times over 30 years and NEVER had this problem before . Can anybody shed some light on this ? ? I am at a complete loss as to what the fix is ? ? Thinking possibly the painter screwed something up when he was working down in that area . Thanks in advance

Take the arms off the posts and rotate the arm 90 degrees so they are horizontal/ parallel with the bottom of the windshield...

Sounds to me like you mounted the motor arm 180 degrees out of position. Detach it from the motor and reinstall it pointing the opposite direction. It should face the driver side of the vehicle in the off position.
