75 WW WIPER SWITCH

[STEPHEN E. MUELLER]

HELP:

1) MY 1975 WW WIPERS DON'T WORK IF MOVED TO THE LOW OR HIGH POSITION, HOWEVER IF YOU PUSH FOR THE WASHER MOTOR SELECTION THEY WILL COME ON AS THE BUTTON IS DEPRESSED. ONCE THE BUTTON IS LET GO THE WIPER'S RETRACT TO OFF POSITION.

2 DOES ANYONE FEEL THAT IT COULD BE A

A) FUSE ISSUE B) WW WIPER MOTOR ISSUE C) WW WIPER SWITCH ISSUE

ANY INFORMATION WOULD BE WELCOMED

Steve,

Just to get you started, and until more expert advise arrives, I'll take a stab at giving you some info. I had some former problems with my 68 WSW system that I won't even begin to describe but going from your info here is what I think:

A) I don't think it's the fuse or you probably wouldn't have ANY function. You might want to try a new one just to check it out.

B) There could be a wiring/connection issue with your motor. Briefly check your observable connections first but before you dig into your motor go to your switch.

C) I think it has more to do with your switch issue. My first thought is that the harness connection to your switch may not be making full contact. You'll probably need to open up your dash at this point and check your connections and go from there. If they are connecting OK then your problem may be in your switch itself (possibly need a new one) or somewhere else. One other place you might want to check connections for is an electrical/vacuum-valve/switch that is supposed to be located (attached) to the back of your tach. If it is attached in the correct place it is difficult to see and reach--Be Careful and PATIENT. If connections to all of these appear OK then I'd wait for more expert information. Hope this can help. Tom

Steve,

Just as a side note, (and since I am only familiar with the 68 WSW components), the electrical/vacuum-valve/switch behind the tach that I described you may or may not have since I think it's application was from 68 to 72 and had more to do with the WSW door that was vacuum controlled. Tom

Re: 75 WW WIPER SWITCH

Stephen,

Here's a thought. I wonder if your instrument cluster bezel is cracked causing a break in electrical ground until you push to activate the washers. When you release, ground is no longer there and the system shuts down. You may try placing the switch in low or high and then playing with the position of the entire switch to see if ground can be made. I think I would pull out the switch and open it up and lube it and put it back in service.

Re: Side-note to the Side-note

Steve,

Just a side-note to the side-note, but you might want to try posting your messages in the "lower case" letters, since I've noticed several of them. You might need the upper case to EMPHASIZE SOMETHING that could otherwise get lost in the translation, especially to someone that's an "amateur" -- like me. Just a suggestion. Tom

Your problem is not related to a fuse. I think that you have a grounding problem. The grounding connector to your switch may have somehow gotten disconnected. When you activate the washer pump by pressing the button, the motor might get its ground through the pump and, consequently, operate until you release the button. The first thing to try is to put the switch in one of the two on positions. Then attach a jumper wire from a good ground source(the engine would work fine) and touch the other end of the wire to the wiper motor case. If the wiper motor activates, you will know that the problem is in the ground connection to the wiper dash switch.
