Problem with blown Fuse 44 (wipers/radio)

10303 Views 8 Replies 4 Participants Last post by  screenshot
I had fuse 44 blow yesterday. I was driving along and decided to spray the wipers (wipers not currently on) and when I pulled the spray seemed a little weak, so I pulled again and BAM, the radio/wipers go dead! I checked and the resevoir for the fluid was empty, so possibly the pump needed to draw too much current without fluid in the tank.

I checked the fuse cover and radio and the wipers share #44. I filled the fluid tank, changed the fuse and started the car....the radio was still dead and I got out and saw fuse 44 had blown again.

Any ideas?? The electrical problem must be caused by the wipers or the wiper fluid pump. It seems unlikely that the radio had anything to do with it. Any insights/ideas would be much appreaciated.

Unplug the connector at the pump and see if the fuse survives.

Grounded!

He may have a grounded pump or the wire under load may begrounded before load.(ie) The wirre grounded togeteher in harnes,or under tape.If the disconect does not work..
I checked the wiper pump motor and it checked out ok, and the fuse still blows. It is strange...the fuse blows on the first click of the key. The wipers shouldn't have power then, right?? The only thing should be the interior lights, radio, etc. Well, I don't have a wiring diagram so I cannot think of what could be shorted on that circuit, so Cosmos may have to go to the dealer. I can't find an easy way to check the wiper motor in front, and I don't have anything in the hatch because I did the rear wiper delete a few weeks ago (btw, I don't think that could have anything to do with this...it is just an open circuit back there, nothing to short.)

I hate the dealer...they fix one thing and break two more!!

Fuse F44 is a hot in accessory (ignition key position 1), run and start line.
It goes to the telephone connector X400 in the center console area, rear wiper unit, washer pump, wiper washer module behind the glove box and the wiper switch on the steering wheel column.
The splice X10022 where it alls comes together is shown to be in the fuse box. The splice is a taped crimped connector.
You could start unplugging things like the wiper switch, radio and wiper washer module.
The line going to the rear lid is a 3 pin connector that I doubt would short from being disconnected unless it got pinched. The two pin hot at all times line is more likely to if not insulated.

Ground

Ron was nice to explain the circuit,pull all the conductors apart at the fuse and find out wich wire is grounded,with out powering it.Turn the key to # one position and see what is dead follow it and fix it,Thats if there all paralled there.Note lucky it is not a high rise building this is childs play..Note most problems start were your hands were last!

Problem solved!!

It became a problem I couldn't tackle with my schedule, so off to the dealer this morning. They found the short in the switch on the steering wheel column for the wipers!!! I can't believe I would have found that in less than 40 hours; the y found it in 4 hours (they had to take the entire car apart to find it though...I think the car was built around that switch!!).

It was the last thing I touched too!! Approximately $415 should cover everything (incl. tax) I was told, and my service writer gave me a 10% discount...I'll gladly pay that to not do that much work. The switch had to FEDEX'd overnight so I'll get the car back tomorrow afternoon. And it is raining out now so its a good thing I took care of this ASAP.

Thanks for all of the advice...this thread should serve as a reference for fuse #44 for the board.

i have the same issue, but it has been going on for quite a long time... the rear wiper kept wiping the glass after i washed it and i think the only way to stop it, was to switch off the car...

then it didnt do this joke for quite a while, but now all of the wipers keep wiping and when i wash the front window, it blows the fuse... when i wash the rear window, it even blows water on the rear glass and wipes it normally, but at the same time, all of the wipers still keep wiping... and again.. when i want to wash the front windshield, it blows the fuse again...

it could be the same switch on the steering column then? -_- (it started to blow the fuse with a hot weather and an empty washing tank... should probably keep the tank always full then?)

i guess it was the faulty wi-wa2 chip behind the glove box, but the empty fluid tank might have also played its part a bit...
how many times does the rear wiper wipe the glass after pushing the lever tho? does it only stop after you push it again?
