Expert:  Ron replied 1 month ago.

The wiring diagram is the factory diagram for the 1995 Ranger. Is that what your working on?

Expert:  Ron replied 1 month ago.

Have a look at the test steps in the link below for the wiper system as well.

the same that you sent me but some wires in my model are not in the same place like the relay and hi&low relay.
Expert:  Ron replied 1 month ago.

Try running the test step in the new link I just posted for you. The relays are located in the under hood fuse panel see them in this link.

I check all the wiring and have continuity but the problem continue. the only i found was the wire in the relays park and hi-lo are in different order but it was working before that way
Expert:  Ron replied 1 month ago.

Did you run the steps I sent you?

Customer: replied 1 month ago.
it no power in the db/o and w but if I jump it the motor its work
Customer: replied 1 month ago.
how do i run the self test in the gem
Expert:  Ron replied 1 month ago.

Power to the Dark blue/orange wire comes from the switch. You need full scan tool to pull codes from the GEM module.

Customer: replied 1 month ago.
i have one but no code shows
Expert:  Ron replied 1 month ago.

If you not getting power from the switch on the Dark blue/orange wire from the switch and all the fuse are okay and you not getting any fault codes then I would suspect you may have a bad switch.

Customer: replied 1 month ago.
ob/o have power and is a new switch
Expert:  Ron replied 1 month ago.

You stated the dark blue/orange wire had to power and also said when you jumped power to it the the wiper run. Is that the case?

Customer: replied 1 month ago.
i remove the relay and jump the ob/o and the motor works same with the white
Expert:  Ron replied 1 month ago.

Okay well something is being over looked here but unfortunately with out being there to do that testing I have no idea what your missing.

Customer: replied 1 month ago.
how do i know if the gem is bad. also i notice that the light in the light switch is on when is off and off when the lights are on
Customer: replied 1 month ago.
that start after the wiper stop working
Customer: replied 1 month ago.
i will do it again
Expert:  Ron replied 1 month ago.

The only way to know if the GEM is failing would be to replace it with a known good unit.

Customer: replied 1 month ago.
the cables in the relays are in different position. did i should change it to the places that the book show it supposed to be or leave it like that
Expert:  Ron replied 1 month ago.

I would not change anything if the positions where working before.

Customer: replied 1 month ago.
ok
Expert:  Ron replied 1 month ago.

Run back through the steps once more and see if there is something you may have missed.

Customer: replied 1 month ago.
the problem is that i have no power in step 5 db/o and w
Expert:  Ron replied 1 month ago.

Unfortunately I have done all I can from here and I can not be there to do the testing for you. I will open the post back up for you and perhaps some one else has some thing else to offer.
