'81 Datsun 720 P.U. I had some engine work done now the heater won't run. I checked the htr. Motor with a jumper and it works. There are 2 relays above the fuse block near the light fuses, but I'm not sure if a relay is the problem. I have a Chilton Manual and it says relays are grouped in the engine compartment at the right fender area. None there. No power at the 3 speed sw. All fuses are good. Does the hot wire go directly to the motor and ground through the switch? Help Please. Thanks Davidseattle
