Recently my heater fan has been acting up. If it comes on when the car is started it will work until the car is turned off. However, if does not work when the car is started, it probably will not come on and turning the engine off and restarting won't help. The A/C and heat are working, if the vents are in outside air mode you can feel a little heat coming in with the heater on and a little cool air with the A/C on. Can anyone help me with what this problem might be? Could this be a belt? I had a heater hose leak a few months back and the repairman broke part of the heater diverter off taking the hose off of it so a fragment may have gone into the heater. Thanks.
