Wipers not working on my 67 Sports Coupe

[phila]

Hi all,
hopefully someone can help me with a problem I'm having with the wipers on my 67 Sports Coupe. I cant get them to go ... Ive looked in the book and it says that the 'circuit breaker' is located as part of the swiper witch.... But before I start pulling the dash apart. I want to know how I can test if this really is the problem .... How can I test the motor?
If the ciruit breaker has blown then can this be reset? or dies ir need to be replaced?

Ive also noticed at the same time the washer isnt working either ..... it was working before....

Any help greatly appreciated

regards
phil

Phil,

I think the clue to your problem was in the statement about the washer not working now either. So I would check the fuse. I'm not in possession of a wiring diagram for your car, but if you have knowledge of where you wiper circuit gets its power from (fuse box, fusible link at the starter solenoid, or a circuit breaker somewhere), you need to just measure the voltage on both sides of this "fuse." If you got juice on one side and not the other, then that part needs to be replaced.

Thanks Roger... I'll look further into it
the only thing I know from the book is that there is a circuit breaker in the actual wiper switch ... I assume I'll have to pull out the dash gauge housing to do it

If there is a circuit breaker it should reset once it cools off. I doubt it has a reset button. I'm with Roger on the fuse.

To test the motor I would think you could find the positive lead from the motor and jump it with some wire to the battery. It may have a negative lead too or just ground to the body.

If the fuse looks good, check the switch.

Thanks Kenny
my gut feel is that its the switch as all the fuses look good ...but I'll take your advice and test the motor first... just a matter of working out which wire .... id really like to find a wiring diagram for it

The switch gets it's power from somewhere, but the fact that neither the wipers nor the washer works now says to me that it is not the switch. These two circuits in the switch are not the same one -- they only have one common connection; in other words -- the power wire.

Does this have a two-speed wiper? If so, it may be similar wiring colors to mine since Ford really didn't change colors much. My 67 pickup has a similar setup as my Falcon. In fact there is a wiring diagram somewhere on this forum Patrick and I both posted to allow adding the intermittent wiper switch into our cars, so I'll find it and maybe that'll help if there is an similarity with yours.

Here's the thread. It appears that the wiper circuit and the washer circuit may not share the same terminals in the switch, but they still likely get they source power from the same place if not indicated elsewhere that they are different.

Hi Roger ,
thanks for your help... the wipers are two speed and the wires leading into the motor unit are Red/Yellow/Green and Black. There is a separate black earth wire too.
I'll go and have a look at the thread too

Phil... ever get your wipers working? We're sure in need of working wipers here in Seattle at the moment...dreadfully miserable here and it made me think to follow-up. :)

Hi Roger
yes they're fixed. As it turns out it was the earth strap that goes to the motor housing from the body (via one of the mounting screws ) simple prob easily fixed ... I did pull out the switch though and check it first .

They ground cars down there to the EARTH! :WHATTHE: Probably helps them stay on the ground and not fall off into space.

Ground/Earth... get it? :ROTFLMAO:

(OK, it case someone doesn't, here we call it a ground wire, and in European countries they call it an earth wire). ;)

Anyway, Phil, glad it wasn't something more serious.
