When the winter weather turns cold,the wipers on my 2009 Silverado 2500 HD seem to lose oomph.They barely make a third of the way up the glass before stopping .A trip through the carwash will usually restore proper function.Anyone else have an issue like this?

I guess Chev didn't design their wipers to operate in colder days of our northern winters.The problem corrected itself with a temperature rise from -32 to -11celsius . All good.
