Topic: wiring mix up from battery??

[jjr]

 Sounds like the mechanical function of the wiper assembly's cams are
functioning. There's a repair kit for the fluid function parts, it's a common
problem.

 But there's no motor in the bottle on my '79...

 When you had the wiper switch out, was the back plate secure and the
terminals protected with the little cover that doesn't fit real perfect?

I will have to pull the switch tomorrow and check what the wires on the switch. 

It does not make sense to have motor on the bottle. I dont even know where it would get its feed from to power it.  Do you have the wiring schemetics of the wipers?

 The wiper motor detail is in the Fischer Body/Chassis manual, did
you get that included in your CD purchase?

 The '79 Pontiac service manual has the up to the connector
diagram, it's pretty well marked.

 Are you going to diagnose the switch?

 Joe

[medicman]

I have the CD and I looked through it, but all I could find was complete electrical wiring schemetics for the whole car. I tried to follow the diagrams but I did not see the wipers in there. I will check the fisher body/chassis manual, I dont think I looked at that part of the CD.

I just want to see where the wires come from to feed the wiper, maybe I will notice something different with the wiring in this car. Could the wiper switch be grounding out in itself?

I am going to look at a complete 79-80 t/a tonight for parts. The fella does not know what year it is, it has been parked in his barn for 15 or so years. He said he would like to get 500.00 for it so if I can use any of the electrical, I will purchase it.

If it has a complete dash, I will swap the wiper switch to see if it makes a difference.

 Here's one of the fine illustrations from it...



 The manuals are a fountain of knowledge, gotta get used to their way of
thinking though...

  It's a simple switch and "IS SUPPOSED" to ground through the black wire
to the instrument panel ground. (I think that's circuit 150 top pic)

  If you get one, try it, but inspect what you have as well...

Thanks for the diagrams, I honestly did my best. I am going to take the cd to work and when I have down time, I will print off the whole damn thing. That might make it easier to follow.

I looked at the wiring today, and I cannot find anything out of place, everything tests good. As far as I can tell.

I hook hose to the wiper washer and put it into a jug of water. The washer fluid pumps like hell for the first 5 seconds and then loses all pressure.
The black cam wheel on the washer unit stops at almost a full rotation and sticks there, so the plunger arm cannot fully move in and out.

No matter what you do, when you turn on the wipers, the fluid want to pump. I dont even press in on the wiper button.

Is it possible to hook up the wiper switch connector backwards?

Elliott

[jjr]

 Nope that connector, like many others, fits one way.

 I have tried a couple of times to repair wiper/washer assemblies,
never with success as there are odd relays and cams in them.

 It sounded at first like it might have just been a switch problem,
especially with the dome light adding to it..., but I think now you
should just replace the wiper/washer assembly.

 Actually, they are not real expensive and you'll want that system
to work correctly.

 I've had two with failed relays, which I could never locate and had
all kinds of odd behavior until I just ponied-up for a re maned assembly.

 The last two I did (replaced with re maned) have worked like new since.

Thanks Joe,

I might just have to buy a new one. wiper motor is new, its just the washer part that is screwing up.

I went to look at the other 79 t/a tonight and it has pulse delay wiper set up on it, could I just take the switch and motor and put it in or is the wiring not the same.

He has a complete car and I am torn on just buying what I need for 200.00 or the whole car for 500.00

For 200.00  I get the complete steering column, rad bottle and washer bottle, 2 perfect snow flake rims, wiper motor and switch, proportional valve and odd bits here and there.

I just dont want to junk up my driveway with a car for the winter. WIFE WONT BE TOO IMPRESSED!!

 Did you find the washer section in the manual?

 Don't make the Lady of the house mad, this hobby only
works right when she is happy too!

she wont mind one more car

[pat]

500 for the whole car is pretty good if the floors and frame are still good

[medicman]

So I have promised the earth and moon to her and she gave me the ok to buy this extra car and it really is in good shape (floors are solid and the frame is awesome), it has been stored in a barn for 15 yrs It has not seen snow or any other weather elements. Its a complete car, with everything power and a very nice T-top.  Anybody need parts!!!

[pat]

pics? why part out a saveable ta

[medicman]

I need some parts, so when I am done with it, it will be a parts car. or a restoration job for someone. Which ever brings in the most cash.

[pat]

the parts will bring more money but not save a good trans am
