Power windows followup

Jason,

I pulled out all the window switches and cleaned the contacts on my 86
5000CS T because the windows would not respond or worked intermittently.
After cleaning the switches the windows worked great for about 2 years but
now they are acting up again. I quess I need to clean the contacts once
more. The newer models have dust shields to keep crud from getting onto the
switch contacts. There is a service bulletin that mentions the intermittent
switch operation. Another possibility is the lockout switch on the drivers
door although this would affect both rear windows. I hope your window
problems are just dirty contacts.
