Wiper issues -- electrical

[hitmachine101]

Hey guys got some technical help needed
my father is at home running all these tests so he has a couple questions
I coped the e mail -- his questions are at the bottom of all this info -- THanks guys for all the help

I ran some tests on the wiper switch on the part's car. I found the switch connector. It attaches to the steering column and connects to the wiring harness. It has 5 pins.
1: Black w/ Blue
2: Black w/ gray
3; BLACK W/ BROWN
4: Brown
5 Brown w/ purple
I applied 12V to the wiring harness end by hooking my probe light to the + end of the battery charger (having the negative terminal hooked to the parts car) Remember the parts car has no power. I got the following results:
1) NOTHING
2) NO LIGHT but I got a relay sound (more on this later)
3) nothing
4) ground (the light went on)
5) ground (the light went on)

I went to the switch side and used my meter to check for continuity (wires being hooked together when the switch is in a certain position)
Results:
Off position: no pins connected (not unexpected)
High position Pins 2 and 4
Medium speed Pins 3 and 4
slow speed Pins 1 and 4
washer pins 5 and 4
remember 4 was a ground

Results: Switch in parts car works:
RELAY Sound: This is huge. This means that there is a POWER relay in the wiper system.
This is a normal way to get power to a high draw motor without running it through the switch.
This saves you money when you buy the switch.

ASK on the forum if the M's have a power relay in the wiper system.
IF so, Is it behind the glove box? and what does it look like? and where behind the glove box exactly
