Question Where on God's green earth is the "Blower motor resistor" on 2000 LS1?

I have a Hayne's manual and while this may sound elementary to a lot of you, it's not to me. Please speak to me like I'm two.

This is what it says:

Blower Motor Resistor
  • Remove the instrument panel. I'm assuming this is the panel for speedometer/odometer, etc. I'm not sure though because nothing says so for certain.
  • Remove the right side heater outlet duct.
  • On vehicles equipped with auto climate control, disconnect air aspirator hose. Is that just what it says it is? A black hose? Should I expect to see it absolutely directly behind the heater duct?
  • Remove blower motor resistor mounting screw, then remove the resistor from the evaporator housing.
  • Disconnect the blower resistor card (is that like a computer card?) from the blower connector.
So before I tear up my car please tell me if I have this right: I can expect to find the resistor behind the drivers side right air duct (after removing odometer paneling), which is in front of a hose.

Just call me Mona Lisa Vito (flexes female muscle)!

There's no pictures so I'm not certain what I'm looking for.

REWARD EXCELLENCE!

OK, there are S-series SL1's or the L-series LS1's(?). Which model do you have? One has the 4cyl engine and the other may have either the 4cyl or V6 6cyl engine. This may make a difference in where the resistor card is located. Misinformation begets more misinformation.......

And is there a reason for this card hunt?

LS1 = L Series 1. I didn't even notice that on my profile (SL1), which I'll fix now. Senior moment. Actually it took me a few minutes to figure out why you were asking, then there it was glaring at me.

The AC fan doesn't function at any speed (or at all) and it was burning as if the resistor went out. What do you think? Should I be looking at something else?

Its buried toward the passenger side firewall on the HVAC box and you may not be able to see it but if you can you may be able to remove it otherwise the glove box, bcm, and other small items have to be removed before clear access is available. Send me an e-mail address for the pdf's if you like.

There seems to be issues about the blower motors and resistor cards in more than one model and the common point may be the ground return for the fans burning wires either at the connector, the connector themselves or at the ground connection. Burned/cooked insulation appears as the obvious failure point.

I'm a young teenager with a 2000 Saturn LS-1. My fan stopped blowing about a week ago and at any speed, any heat level, or any setting the fan will not blow (however I do feel the heat). It was blowing intermittently for a few days, the completely stopped. I took it to my grandfather's garage and he sanded down the oxidized fuse under the hood. That seemed to work however the next day (today) it stopped again when I was pulling into my driveway.

What is the issue? I just purchased a volt tester which should help in testing the electrical connections. I have downloaded an image of the wiring scheme of the HVAC blower motor from this forum however I need more help. Any ideas? Thanks.

See pics below. You may have to look under the passenger side for blower wiring or look under the cabin filter cover to find blower wiring for signs of discoloration in wiring to indicate over heating. The HVAC control head may have to be removed too for examination of wiring.
