Blower Inhibit Switch
Location: Installed in a brass boss that is brazed to a steel
"T" fitting which is inserted into the heater return hose on the
passenger side near the firewall.
Function: Inhibits the Heater Blower from engaging until the
coolant temp reaches 110 degrees F to prevent introducing cold air into
the cabin when heated air is in demand.
Location: Installed in the lower intake manifold into the lower
intake's extension of the engine water jacket, specifically between the #2
and # 3 intake runners.
