i am looking for the wiring diagram for the blower motor and blower speed control switch

 

You might try your local library for a service manual or some of them have acess to www.alldata.com
You can also purchase a 1 year subscription at www.alldatadiy.com which has great wiring diagram and a ton of other info.
I don't have a manual for that year...might find one real cheap on Ebay also.
