[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Hi Danny,
The problem that you describe also occurs on my 83X and on many other 1500 cars. When I place my wipers in the intermittent mode, they will give a couple of strokes, then stop mid-stream in the third stroke. The voltage will drive down in the 10-11V range, and as you say is probably a function of both high resistance in the circuit and frictional losses from the wiper motor. If you place the wipers in slow (second position), the mid-stroke pause should go away. Similarly it should not be present at high speed (third position). I have not yet had a fuse blow from this problem. I through the circuit and cleaned all the contacts and also lubricated the wiper motor. This helped a bit, but I still have the voltage drop. As far as the strange intermittent frequency, I think the problem is in the delay mechanism of one of the relays. I'm at work right now and don't recall the details. When I get home I'll check my electrical diagnostics manual and drop you a note with more details.
Best wishes,
Mike

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Fuse B controls the wipers and voltmeter (as well as many other things). A tarnished or weak contact on that fuse would cause this problem.
The wipers shouldn't be able to stop midway, once the wiper delay has moved the wipers from park position then the park switch in the wiper should take over for the rest of the stroke. Possible that the switch is acting up, but you would probably also notice that the wipers wouldn't park from slow/fast either. Maybe they just didn't have enough power to keep moving?<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->It's because the circuit uses a mechanical delay relay, with a heated wire. It takes 2-3 wipes for the wire to warm up the contact enough to break the circuit, at which point it cools/heats at a regular pace.
If you've ever stuck those special blink-lights in your christmas light string - exact same principal and you can see through the glass how it works! (note also, your xmas lights take a few seconds to start blinking too)
Only way to fix it is to replace the mechanical delay relay with an electronic one. Wiper delays are available in auto parts places and could be used. I've been tempted to do this, more for the ability to adjust the delay than to eliminate the 2-3 wipes.

As the others have said also... clean up everything in the wiper motor's electrical path and it might help... But it should never stop mid-sweep.
Good luck... sounds like another candidate for an additional relay mod like the headlights!

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->Fuse B controls the wipers and voltmeter (as well as many other things). A tarnished or weak contact on that fuse would cause this problem.
The wipers shouldn't be able to stop midway, once the wiper delay has moved the wipers from park position then the park switch in the wiper should take over for the rest of the stroke. Possible that the switch is acting up, but you would probably also notice that the wipers wouldn't park from slow/fast either. Maybe they just didn't have enough power to keep moving?<!-- google_ad_section_end -->

[FONT=Trebuchet MS, Verdana, Tahoma, Arial]<!-- google_ad_section_start -->It's because the circuit uses a mechanical delay relay, with a heated wire. It takes 2-3 wipes for the wire to warm up the contact enough to break the circuit, at which point it cools/heats at a regular pace.
If you've ever stuck those special blink-lights in your christmas light string - exact same principal and you can see through the glass how it works! (note also, your xmas lights take a few seconds to start blinking too)
Only way to fix it is to replace the mechanical delay relay with an electronic one. Wiper delays are available in auto parts places and could be used. I've been tempted to do this, more for the ability to adjust the delay than to eliminate the 2-3 wipes.

As the others have said also... clean up everything in the wiper motor's electrical path and it might help... But it should never stop mid-sweep.
Good luck... sounds like another candidate for an additional relay mod like the headlights!
