Labtec Posted December 6, 2005 Share Posted December 6, 2005 My 92 SC400 does not dispense any windshield washer fluid. I cleaned the nozzles and the washer fluid lever is full. When I try to spray it, I don’t hear the motor (pump) sound. What could be the problem (pump, fuse)?? What steps should I take to diagnose the problem? Thanks, Winny Quote Link to comment Share on other sites More sharing options...

Naslund Posted December 12, 2005 Share Posted December 12, 2005 I do have exactly the same problem. The windshield washer fluid doesn't dispense out and I don't hear the pump working while spraying it. I guess this is another SC400 chronic problem as well?

jzz30 Posted December 12, 2005 Share Posted December 12, 2005 did you try the pump? Quote Link to comment Share on other sites More sharing options...
Naslund Posted December 12, 2005 Share Posted December 12, 2005 Could it be the fuse for the pump? I just bought this car so I don't even know where the fuse boxes are. lol Quote Link to comment Share on other sites More sharing options...
JIBBBY Posted December 12, 2005 Share Posted December 12, 2005 Could it be the fuse for the pump?I just bought this car so I don't even know where the fuse boxes are. lol ← You will find the fuse box next to the battery, it is in a big black plastic box, you will need a screw driver to remove the top, there is a second box that would be on the driver side next to where a foot pedal clutch would be against the side right above the carpet. So again as you bend down under the steering wheel, look to the left and up behind the carpet and you should see the fuses. That is the box I believe is where your fuse is if bak. Try the engine box second. You will need a fuse puller or needle nose pliers to pull each fuse out on at a time, til you find one with a break or burn on it, and that will be your bad fuse. Try that if that does not work, it will most likely be the motor. Last the wiring. Good Luck. Quote Link to comment Share on other sites More sharing options...
Naslund Posted December 12, 2005 Share Posted December 12, 2005 Thanks Jibby! I will check the fuses tonight as you described. I'm really hoping it's the fuse causing the problem. ^^; Quote Link to comment Share on other sites More sharing options...

If it does end up being a fuse, and you change it and it goes bad again on you, that means it is the wiring causing the problem, and you probably have a hot wire exposed and touching some metal somewhere. That is a pain and in most cases you just need to run new power and ground wires to the motor, forget about locating the source of the short and replacing that section of wire, too much work, and still won't be as good as new wiring. Good luck. Quote Link to comment Share on other sites More sharing options...
