[img]smileys/smiley11.gif[/img]92 Park avenue..I am having intermittant issues with the fan for my heater/defroster.. it is not a fuse, checked that.. everything else seems to work ie. with the heat on it comes out the vents with no air driving it.The fanworks some days and not others..If I leave it on when it isn't working while driving it will just come on when it wants to.. sometimes it doesn't.. nothing I do like shut it off and back on seems to have any effect.. is their a sensor, or relay or something that is tripped? help.. anyone know what is going on? ol hounddog is little [img]smileys/smiley19.gif[/img] new tires, new alternator, new struts up front, new breaks and wheel hub assembly up front. now can't even keep myself warm.. hoping for an easy fix, from some smart buick owner that had a simular issue..
