97 cadillac deville heater controll
it is on the passenger side right next to the windshield under the hood it is black and has a purple and black wire connected to it
It is at the rear of the intake manifold, follow the heater hose. there is a flow door under the dashboard with a cable connected is that the control or does the valve body at end of intake still control it?
First thing to check is coolant level in radiator ( not the overflow jar ) , NO HEAT. If you are savvy, feel heater rubber coolant hoses going into and out of heater core. If neither or only one of them is warm , PROBLEM. Open radiator cap ONLY when cold to check level. Make hose temp check at engine operating temp. It could be a bunch more problem . but these are the obvious, and first ones to check. Good luck
Behind the intake plenum on the passenger side.
Check the A/C fuse, that's what happened on my '85.
