My wife's '98 Sentra SE developed this problem shortly after I replaced the dogbone motor mount (surely unreleated) the blower stopped operating on 1,2 and 3 but blows on 4. Is this something anyone has seen before? Should I go after the switch or the blower motor? Heath ===== Heath Vogt BSME '69 Baja Bug - Brutus "the wonder bug" '01 Isuzu Trooper '98 Nissan Sentra SE
