W900L blower problem

[Waterloo]

You should have a fresh air filter somewhere in the system. Mine is under the hood at the fresh air intake up at the passenger side firewall, on the windshield wiper cowl. Replace that, needs to be done quite often, or more than most guys think. Then pull the blower motor, like Chamberpains said, it is probably toast. FleetPride probably carries it, will be much cheaper than the dealer. When you get the blower out, clean up any crap in the box and inspect the blower motor wiring for chafing or other damage.

Also, under the hood on the passenger side, you will see one or two flat tubes, that is where your AC condensation drips out. Pinch those to open, get the dirt and other crap out of them. Should be right at eye level.
