96 8200G Windshield Wiper Wiring

The switch for my wipers has 3 positions (off, high, low, I think) but someone has hacked the wiring up such that I only have 1 speed that operates when the switch is in the "off" position. To turn them off the switch has to be in the "high" position, which causes them to halt where ever they are, rather than returning to the lowest point of their sweep, aka the "parked" position if that makes any sense. My wiper switch is located on the turn signal switch, which is self-canceling if that matters. The washer fluid pump is also not working, but I haven't done any troubleshooting so I don't know if the pump is bad or just not getting power from the switch. I'm hoping someone has a wiring diagram or can tell me where I can get one. I'd like to get a complete service manual, but my research leads me to believe those don't exist for us regular folk. I'm still holding on to hope that my truck is old enough to make one obtainable, though.

 

The VIN is 1HTHH0003TH245444. I'm not sure what switch setup I have. It is on the turn signal switch if that helps. I will go and get pics and post them.

 

Thanks! I will PM you as soon as I can. I have to make a few more posts before the system will let me send a PM to someone, so bear with me for a bit.

 

I got it, just in case you didn't get my reply email.
