great i will open the hood and put my ear as close to the fresh air intakes, and listen for the blower motor running while the climate control is in the o off setting,if i hear the noise i will assume i need a new climate control unit.the noise is constant when the key is on,it never goes away,thanks for the input.if i find the blower motor making the noise,i mean what else could it be right?then i will oil the bearings,is it true that the blower motor can only be accesed thru the underhood wiper area? and not from under the dash board area.
