Lost heat. Fan works, fluid full, checked two 25amp fuses marked htr, heater core not leaking. Have new thermostate & housing-not leaking. One week ago had to start motor with start mode on my charger. Lost heat & temp. Gauge quit working. Only time trouble starting & no problem after, but seemed completly dead at time. Not even a click noise. Did I burn my heat sensor or is there another fuse to check?
