[DML] Re: Fan blower motor

["daveswingle2" <swingle_dmc@xxxxxxxxxxx>]

I've only see the 1-wire setup on extremely early (sub 800) cars. The 3-wire ground is normal. 

Water gets in from outside if you pressure wash it in the front under the windshield, very occasionally in heavy rain with wind, and usually from a blocked A/C drain than causes the condensate to back up into the housing and slosh around. While you have the motor out reach in to the eft and check for leaves. Also find the drain under the car near the A/C bottle and try blowing through it.
