It would be in the glove box or trunk.
what is the fifference between a saturn sw1 and sw2
Which one? There are several relay's on the Saturn. Relays are used to operate the horn, AC and fuel pump, to name a few.
If it now works it could be a bad connection to the sprayers.
No. To remove the widow its easiest to remove the outside panel
You need a fuel line disconnect tool. Slide it over fuel line and push towards the connection and pull, the line will come off.
if its FWD then the starter is under the intake manifold and fuel rail at the bottom of the motor in the back by the firewall
I could not find a "SW2" in my reference materials but I did find "S-Series" vehicles. 1. Step 1 is to be sure you get the right replacement wiper blade. The 1997 Saturn S-Series vehicles take a 15" rear wiper blade (drivers side is 22" and passenger side is 21" - fyi).
