OK folks, I am just returning from the shop. Regarding Heater Motor-- I put in Battery, turned key to ON, Pulled Connector from the Heater Controller on the Heater Box. Hooked up Test Light to the connector ends, grounded the test light, Test Light shines on all three positions. Grounded the Test Light to the front of the Heater Box, and to the Stud that holds the Heater Box in place on the front. Test light shines. So, the switch in the Dash does exactly what it is supposed to do and the Heater Box seems to be Grounded to the car at least on the Front side of Heater Box.
Took out the Heater Controller from Heater Box, hooked Positive Battery to one of the Inbound prongs, test light to the outbound prong to the Negative, Light shines. Tested all three prongs, Light shines.
Replaced the Connecter from the Outbound Heater Box Controller wire (green one that goes over the top of Heater Box to the Motor), hooked directly to the battery Positive, grounded to a good ground, No Heater Motor movement. I reached into the Heater box and manually spun the heater Fan Cage, it is free and looks good.
Finally hooked battery Positive directly to the green wire that goes to the Heater Fan, reached up under the Heater box and tried to ground to the back of the Heater Motor, Nothing.
So, hooked up Battery Positive to the green wire that goes direct to the Heater Motor and took Test light from Negative Battery
terminal to back of the Motor and got no light. Here are some pics of the Heater Controller on the Heater Box. It looks and works good.
Any ideas folks? B.
. Here is a pic of where the Ground wire hooks on the back edge of Heater Box. Look closely, you will see my Negative Black Wire that goes to a Screw on the back side.
