Blower motor does not work on any setting. Blower motor works fine directly connected to battery or in another Saturn. Blower resistor impedences test good. With blower connector disconnected and blower switch on, 12V is at the blower connector; but connect to the blower and nothing happens; back probe shows 0V. Also, it may or may not be pertinent but disconnecting the battery for 30 minutes and reconnecting, then waiting about 10 minutes resulted in the blower working for a couple of days, then the same failure. Replaced blower relay and verified fuses good. Help is appreciated.

You go in from the engine side . Disconnect the negative battery cable.Remove the super blade assembly, both. Pull up the cover that houses the interior filter and remove. Remove the wiper motor assembly.The blower is directly under it. Remove the four screws holding the blower cover on and remove.There is only a flat black plate that holds the blower in place .Disconnect the power line running to it, and pull up.
BY PASS SWITCH BY RUNNING A FUSED JUMPER WIRE FROM THE BATTERY POSITIVE TERMINAL TO WINDOW MOTOR CONNECTOR, HOT SIDE, AND A NEGATIVE WIRE BACK TO BATTERY NEGATIVE TERMINAL...IF WINDOW OPERATES....IT IS THE SWITCH
Hey Glen,are you saying the blower doesn't work sometimes,if so then your blower motor resistor could be bad,it's located next to the blower motor,easy to remove and replace.Here's a guide to blower motor.
There are 2 different engines for the 92 SL,they are 1992 Saturn SL 1.9L TBI SOHC 4cyl 1992 Saturn SL 1.9L MFI DOHC 4cyl Here's a link to the blower motor resister,it's located next to the blower motor,2 screws hold it on.
Should be on the passengers side under the dash.You might have to remove a panel to see under the dash.Make sure you are getting power to the blower motor before you replace it.If your not getting power then it is not the blower motor.Hope this helps.Good luck.
check the hvac fuse. if its ok you can check the heater control resistor. its mounted in the heater box usually on the passenger side under the dash. these are cheep and available at your local parts store
It is not feasible AT ALL to repair the blower motor resistor, will fail again, be better to take a little trip down to a salvage yard and see if there is a lower mileage car with one.Or try to possibly locate one off line maybe, HOPE I HELPED!!!
