BLOWER MOTOR RESISTOR GONE BAD

2000 Saturn L300 • 6 cylinder FWD Automatic • 97,500 miles

I have a blower motor resistor that has gone bad in my 2000 Saturn L300 a.K.A LW2. Could you please tell me what the right tools to use are to complete the replacement? Nut driver size? Phillips size? Any other tools needed? What's the easiest way to unclip the red retainer clip to get the old board assembly out? (I read 30 minute job, took me three hours last time: ()

All you need is a #2 philps screwdriver and a flat blade screwdriver to remove the plastic clip's there really is no secret way to replace them. There not the easiest screw's to take in and out but other then that it's not too bad of a job. Here's the repair manual's instruction's I will post for you but they say to remove the glove box which I have never had to do.
BLOWER MOTOR RESISTOR

REMOVAL

1. Disconnect negative battery cable.

2. Open glove box door.
3. Remove glove box lamp assembly by pulling on lamp plunger.
4. Disconnect glove box lamp wiring harness from glove box lamp.

5. Remove right side I/P lower dash insulator retainers.
6. Pull insulator rearward to detach from forward insulator retainers.

7. Remove right side heater outlet assembly retainer and remove outlet.

8. Remove glove box door.

9. Remove glove box bin fasteners.
10. Slowly remove glove box bin tilting bin downward to expose the BCM module residing on top of the glove box.
11. Remove BCM module from glove box by sliding module out of attaching slots.
12. Remove glove box bin.

13. Disconnect recirculation actuator electrical connector.

14. Remove blower motor resistor screws.
15. Use electrical harness to pull resistor card out of module.
16. Disconnect blower resistor card from electrical connector.

My Saturn LW300 blower motor would go on, off especially on bumps in the road.

I followed your description on the diss-assembly and that got me to the resistor pack. Since I could wiggle the wire to the pack I knew there was a loose connection there.

I removed the resistor pack and slid off he white cover. There is a small circuit board. The board is not removable. You will break it if you try.
I soldered every connection very carefully avoiding any shorts. Be sure to heat the large connectors well allowing solder to flow freely.
This makes sure that the connections below the circuit board are refreshed.

I re-assembled the resistor, actuator motor and circuit plugs and tested it.
It worked perfectly,

Re-assembly of the glove box went well. My wife got the job of replacing all the stuff that was in the glove box.
