could it be a vac leak? i read some where about the vac on hub leaking causing a vac leak affect their heater or vents or something. my bearing hub assymbly is pulse vac and its been needing replaced and now i blew it out on a long trip south. im hoping replacing it will fix my vac leak to get my heater and vents to operate correctly. im doing it in next cpl days so ill let u know if its the prob
sorry to jack ur thread its just i was having same problem and my bearing was going out and certain 4x4 are pvh and cant find the vac leak. maybe the light has something to do with being fudged from hub vac leak. i could be wrong tho about everything lol
just my 2 cents
