Delay Wipers uncovered
-UPDATE- I've developed a functioning switch and you can see more about it, as well as order one on the following website: https://sites.google.com/site/huntersswitch/
I searched to the ends of the internet and wasn't able to find anyone who was able to break the code on how to make a fully functioning home-made version of DSE's "Selecta Speed" wiper motor - so I did it.
Here's what you need:
- The ability to solder
- A wiper motor and pigtail* from a 2000 Cadillac Deville*. (1. You can reuse the pigtail or order a new weatherpack connector if you want to // 2. Wipers from other GM makes & models will work - this is what I used and what my wiring diagram is built for)
- A rotary switch with at least 8 positions
- The required carbon fiber wound .25 watt resistors
- Lengths of 14ga and 22ga wire
What you'll need to do if you want to remove the motor from the junkyard:
The wiper motor is on the drivers side of the cowl, underneath the plastic wiper blade cover plate. You'll need torxs bits to remove the motor from the bracket as well as metric sockets. The wiper arms need to be removed in order to gain access, so bring a pry bar. I also brought a battery operated sawzall to cut down the mounting bracket. You don't need the bracket, but I got it to make hiding the motor under my fender (68 Camaro) easier - I can just trace the mounting holes easier.
When complete, the wiper will have a "mist" setting, 4 different delay modes, low and high speed. There is also an option to have the wipers make two passes when you use your windshield washer. As with the DSE model, this wiper motor does not have a washer pump - so you have to rig up a separate switch. I've got an idea of how I will do that, and will post details if/when I do it. I would like to find a rotary switch that also has a push button feature or a momentary first position on it, but haven't sourced that yet. If I do, you would then have a full functioning wiper motor from one switch, just like in the Cadillac (or most other modern cars).
Switch settings will result in the following:
1 - Off
2 - Mist - 20 second pause between wipes
3 - Delay 1 - 8 second pause
4 - Delay 2 - 4 second pause
5 - Delay 3 - 2 second pause
6 - Delay 4 - 1 second pause
7 - Low (continuous)
8 - High (continuous)
Other helpful hints before I get into the wiring diagram - if you're wanting to play with modern parts on an older car - try looking at Auto Zone or Advance Auto's website for wiring diagrams. I think I used Advance Auto (can't remember) and after signing up I had access to Cadillac's wiring diagrams - incredibly handy.
Below is the wiring diagram from Cadillac:
Below is the connector details
I'm waiting on my battery to charge on my camera then I'll be able to post a movie of the motor - in case you want to verify it works.
Another note in case you're wondering - the motor will self park. So if its in mid wipe and you turn off the switch, it will move back to its parked position. This motor will not however work for those with hidden wipers that need to 'retract'. I believe I've seen a post on how to modify the motor to work for hidden wipers, but since my Camaro doesn't need them, I didn't pay much attention to it.
I may solder it all up tonight or tomorrow, and I'll post pictures of how the switch looks with the resistors when that is done.
Let me know if there's any interest in more details - I'll be glad to help out if I can.
