relay part numbers and specs for wiper switch and window modifcation
So my window switch keep burning up and I figured it was because of the large current draw passing through those dainty little bridges. Anyway I found a thread mentioning the relay fix which makes more sense to me than the MPV stuff.
There was a word document that unfortunately I could not open, I am assuming there were some specs on the relays needed. Does anyone know either part numbers or specs on these. Also the wiring diagram I found appears to do nothing it looks like the relays have power and ground as long as the ignition is on and are always closed, and the current draw of the motors still goes threw the switch?
Also I want to replace the relay in my wiper switch so I will have more than one wiper setting. I searched today but did not find the relay part number. It is the same as original? Can I just call Mouser and give them the original number?
Thanks guys

Makes sense to me.
With a de-energized relay:
30->87 open
30->87A closed
energized relay
30->87 closed
30->87A open
Now, follow the ckt. Press 'up' on the switch, the upper relay will energize, shutting the contact between 30 and 87 shuts, putting power to the motor. The lower relay remains de-energized so the contact between 30 and 87A is shut, grounding the motor. If you push down, the same thing happens, but the relays are switched.
With the switch in nuetral, both contacts for the motor are to ground. Those are probably just your typical $4 relays you get at Radioshack.
You don't have to worry about this if you buy my car, because they are of the cool manual kind.

ok I see it now
86 is the positive side of the coil
85 is the negative side of the coil
30 is the common of the "switch"
87a goes to ground when the switch is off
87 goes to power when the switch is on
I was confused about the pins on the relay.
(I called you last night about the car, I'll call again tonight)
