Nar, tear off to the wreckers & buy the whole slide set up bit.Should only cost ya $30 if u go 2 1 of thoz u pull it joints.The Fan switch itself is what's pox on it.Gently undo your on whole damm dash, stereo facia included & carefully undo the Heater Actuator leaving all the vacuum hoses assembled on the rotator thing.They are numbered at the factory to help with instillation for the Bi-level, foot, vent ,etc postions.If one of the hoses cum adrift you'll have no air control in that corresponding area & a serious vaccum leak to go with it.Be warey thou as the stickers often fall off thru age & maybe not even there..
