My windsheild wipers stop in the up position on the delay setting but park all the way down when turned off. How do I fix this
You will need to diagnose this with a multi meter....on dark green terminal d at the wiper pulse board, with the wipers on any delay position, you should be reading .0005 Amps and 12 Volts and at the same time on the delay position one click below low(the fastest delay speed) you should be reading .0003Amps and 12V on terminal E gray wire, The purple wire (terminal C) should have 12V on high speed only. The yellow wire (terminal B) should have 12V when the key is on and the black wire (terminal A) should always be grounded....check all of that and we should be able to find your problem.
The Amperage should change on terminal E (the gray wire) with each position on the switch but the change will be very small. i.e. the first speed (longest delay) will read .000017 A, the second setting .00004 A and so on. Check that and let me know...(by the way, amps are checked in series with the connector so unplug it, place one probe in the connector and the other in the motor plug terminal. )
