2001 Camry CE Wipers Only High Works
 

Neither intermittent nor slow speeds work.
They both stopped working suddenly.
Fast speed works fine, however, wont automatically park.

Is there a winding/circuit difference between slow and fast speeds ?
I suspect what ailing intermittent is also causing slow to not work.

Any insight / direction appreciated.

An update after a little investigation..
As suspected only a single fuse so not that simple.
Exposed the motor and it it's a bad connection at the wiring connector.
Anyone know which one(s) are exclusive to slow/intermittent ?


Thank you,
Jon

As to wiring:

Blue is DC power from fuse.
Blue/Yellow goes to the motor park switch arm.
Blue/Black is low speed and intermittent.
Blue/Orange is high speed.
White/Black is ground.

Thank you for the details.

It looks like my problem is the connector.
If I seat it firmly it'll stop working.
If I seat it lightly it works.
It's back together for now.
If it messes up again I think I'll try giving the prongs that stick out from
the motor side a little bend to help make contact.

Thank you,
Jon

If it is the plug terminals might clean them with contact cleaner, sand paper, eraser end, etc.

Yes, good idea.

I had used a small jeweler's file but that didn't appear to help.

Perhaps after inspecting each plug you can determine if the pins are removable.

They generally slide in from the back of the plug and are retained by a spring clip incorporated into the pin. Installing a thin narrow screw driver or round probe, etc into the front of the plug will force the clip portion of the pin down and allow the pin to be pulled out the back of the plug by the wire it is connected to. Then the pin can be easily cleaned and reinserted into the plug.
