Thanx!

The meter I'm a little iffy on fuses are all good and dash lights do work I've tracked down all the grounds "I HOPE" n are bolted down.Seems my circuits are just dead from the 3 plugs on driver side fender back,also when i turn blower motor on "dont work" the lights in the heater controls go out could motor be shot? Its the 1 out of the donor truck and i never tried to run it.Electrics have NEVER been my strong point. THANX for your time n help!

There is a good possibility your blower motor is just the resistors gone bad, Quite a common problem.
