Report "2004 Pontiac grand prix blower motor.... I had a problem with the blower motor running when the car was off...replaced the control module...now the blower motor isn't working at all. Had this problem before. Took motor apart and greased the brushes. Work good but figured wouldn't last long. I now bought new blower motor and still nothing. Is there anyway water could be leaking down around the cowl and got to the module that i just replaced and it is bad again. I checked the cabin filter and the little rain gaurd was off so I re-installed it. Also...several times down there messing with the wires out of the module to the motor...it would kick on for a second. Have power going to the module on the red and black wire...dont know how the test from the switch..just know there is power going to the module..but not out....please help....thanks"
