What are my A/C options?

What are the options to fix a high pitched shrieking AC Heater blower motor in 98 Olds Intique?

• Answer:

  I have Olds Intrigue 2000. Lately Blower started acting up. Stops working, an hour later it will start working again. Making shrieking / squicking sounds, speed changes while driving. Using 5.5 mm socket I removed the old motor. (Not very difficult.) Wiring harness is a bit tricky to unhook. (!!!Do not touch the orange clip!!!) Use screwdriver to push the Black Clip in. Inside the old motor I found brushes are completely worn out. Needed new motor. Replacement Motor: In Riverview Florida: Napa and Pep Boys have Chinese made blower, just different stickers on them. In my case Napas had wrong connector type, Pep Boys unit had no connector at all. Local Chevrolet parts department and Advance Auto Parts had similarly looking part with more or less right connector type, just different stickers. Both made in Canada. ---------------------------------------------------------------------------------------------------------- Answer I tried the wd 40 route and it did not work. My next try will be to replace it. Replace it with a new one. Eventually it will stop working. the shrieking noise is the bearings in the motor worn out. I repaired the shrieking blower moter on my 99 intrigue by taking it out and shooting WD-40 into it, spinning it manually for a few minutes. This took care of it. Did not have to replace it. These motors have brass bushings that go crazy if dirt gets into them. You can access the motor bushings through the drain hose hole in the side once the motor is taken out. The motor is located below the glove box behind a panel. Remove the panel (three snap fasteners, and you will see the motor. Three hex head screws hold it in. You also must disconnect the blower by pulling the connector apart. The connector is one of those snaplocks, use a screwdriver to pull down the orange clip to release the connector. I tried the WD-40 route as well and it did not work until I sealed the bottom bearing with Vaseline. Since then it spins without squealing. It's cheaper than buying a new/used one!
