Previous Thread Next Thread Print Thread Rate Thread Heater Only Blows Hot When I Am Moving #358507 12/05/03 05:36 PM Joined: Nov 2003 Posts: 57 Austin, TX distilled OP Getting the Wheeling Fever My heater just started doing this. It does not seem to be putting out nearly as much heat and when I come to a stop, say at a traffic light or something, it starts blowing cold air. Starts blowing hot again as soon as a start moving. Engine does not appear to be running too hot or too cold. What could it be? 1991 4Runner V6(3VZE) 5-Speed 4X4 SR5 349,000 Miles and STILL Running Strong!!!

If it's not closing your engine temp may just be low.
