Few weeks ago it was real cold (-40c with wind chill) so they weren't spraying unless i drove for a while---but i could hear them trying to. Warmed up a week later and they worked fine. Week later got a yellow bulb failure light coming on and sometimes not for a few days, all lights seemed to work fine, havn't seen it since. Not long after i noticed the pumps wern't even making a sound like they were trying to spray. Topped up the washer fluid, changed out a blown fuse (fuse 8 according to diagrams i seen) and happened to be going on a 4hr road trip--so you'd think they would have warmed up enough(-20c right now) but they still arn't working. Could there be another fuse blown? Could it have anything to do with the light bulb malfunction i had a while ago?
