Not sure if I posted this to the correct Forum previously so...I have a 2010 F-150 XL. Recently the AC fan started working only intermittently. Now, when the fan doesn't work the wipers won't work. So, as it is an "off and on" problem I don't think it is fuse related but wonder if, somehow, both systems connect through the key cylinder or otherwise have a common connection. Anybody have any ideas?
