why wont the heater shut off


Asked by Feb 03, 2016 at 09:38 AM about the 1990 Chevrolet Corvette Convertible

Question type: Maintenance & Repair

heater runs after motor is turned off

1 Answer


If your talking about the blower motor, my info shows two blower relays, high speed and low speed relays, pull the relays, see if it kills the blower. Depending on the vin, there is a fusible link, that sends voltage to load side of relay, that fusible link is hot all the time. Could be relay problem or the hvac control, the hvac control sends voltage to control side of relay. w/o doing some testing I can't tell you which?
