The Hi Blow relay is on the firewall just above the evaporator box, the contact on the bottom has a habit of burning off

81 it feeds right off the fuse link, no fuse. Livin on the wild side

Well I was thinking that it is either the relay, resistor, or the fan switch in the console.

Resistor is out of the circuit on High. If the Hi Blo relay picks up the switch is good
