Wipers working / washer always on?? anyone experience that?

[[JP]]

Hi all, little help here please...

the wipers on my truck were wired to a simple on/off switch, but I managed to get hold of an original wipers switch for my 65...
I have a 2 speed motor, with a built in washer pump. However, the washer pump is broken so I wired in a new universal washer pump.

I wired it this way:


ignore where it says washer motor, should be wiper motor.
I got the power for the new pump off tab number 4, not fuse box.
I have also disconnected the jumper cable from tab 4 to the washer motor as no need to activate the old washer motor as its broken.

After finding all the original wires still there, (cut) behind the dash I connected everything using test wires and all worked fine.
2 speeds on the wipers and washer when I pressed the button - as can be seen here on this video ---- https://youtu.be/Rl9BGHhrqUk



Done some proper wiring, all soldered and sleeved, put it all back in and now my washers come on as soon as i turn the ignition on and won't come off.

could this be the switch sticking? I've tried tapping the switch and pressing the button a few times, but no change.
has this happened to anyone? can the switch be opened if its something inside it?

thanks!
