2 speed wiper motor

Hello I have a 1967 dart I'm having trouble with the wiper motor. when I turn the switch off, the wiper stops at any position. It will not go to the park position. How do I adjust this? Thank You jeff 67  

can you get to the wiper switch and connector..?????

there are 4 wires into the wiper motor.. plus a ground ...

i only have the wiring diagram .. not the wiper diagnostics pages in front of me..

wire colors to the motor

dark green

red

dark blue

brown

the above wires are connected at the bulk head connector and continue inside to the wiper switch..

the wiper switch has those 4 colors  and 3 more

there is a brown TR wire...  probably a brown with a stripe of some kind..   that goes to the wiper pump...

WHITE    this should be switched power... comes on with the key... it will also have a fuse as some point.. which fuse is not clear on the diagram...  it also runs other things like the back up light power and into the console if you have one..

PINK...  this should be constant battery power...   and probably fused...    this power source  should also pass through the switch and continue into one of the first 4 wire colors i listed...   this provides power to the motor for parking the wipers...

there is an internal switch that keeps the constant power hooked to the motor windings till the motor is just about to the right position.. then it will stop...

check for power to one of the 4 wires at the motor with the IGNITION switch on the wiper switch off...

if you do not find this power.. you have found the circuit to check.. but which wire... ?????

there should be power on a different wire with each switch setting on the wiper switch...



so... with the key on.. wiper switch off..   there should be power on one of the 4 wires at the motor...

with the key on... and the wiper switch on high ..   the above wire should have power and ONE other..

with the key on... and the wiper switch on medium.. the above wire and a different wire..

with the key on..  and the wiper switch on low...      the above wire and the 4th wire...

perhaps you could post which wires you find have power at which position of the wiper switch.. so all the people who are going to read this will know...


so the motor could have a bad internal switch

the bulk head connector terminal could be broken or corroded..

the wiper switch could be bad...

one of the six fuses could be bad...  blown... loose.. corroded..
