Need HVAC wiring diagram

anyone have a shop manual? Checked my Haynes (I think) book and nothing in there.

Heat's not working, blowers good, might be the relay but I need a wiring diagram to check it out.

Thanks

I need to know the year and engine size and I can get you a diagram

I need a diagram for a 95 Avenger w/ a 2.0 4 cylinder.
