I have a 87 cherokee. My front windowwasher pump is a little funky.
If I have the power cable pluged into the pump, my windowwipers wont work by pushing on the silver tab. They only work if i actually turn them on.

Then if i disconect the power, the silver tab will make my wipers go once.

Does anyone have any idea what is wrong?

Check your ground and any other electrical connections.
Ok, i check the wires. The front has a purple and a black wire. The purple seems fine, but the black one looks liek someone has messed with it before.

The black wire from the pump is joined to the black wire that contines down the line. __L___ like that with the L being how the black line from the pump connects to the main wire.

Do you have a wiper delay? If you do, pull the module out and plug the wires together and see what happens.
