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?
