Air wipers will not work in cold weather
I own a 1995 Freightliner. The wipers work with air. I live in Quebec where the winters get
pretty brutal. Towards the end of last winter I noticed my wipers were not working too well.
They would just not work and with a nudge here and there, they started to work. Then,
summer came and I had no problem. Recently the winter has started very cold and now
my workers have a tough time getting going. Any thoughts?
That sounds like water in the air system is freezing, have you installed a water separator/dryer in the air system?
