Suzuki Reno 2005

Heater works when it wants. Doesnt have a pattern, its just random. No coolant leaks. HVAC fuse is good. filter and hoses clog-free. i dont know what else could be wrong.

  1. I have an easy test for you to perform if you would like. The next time you have no heat(and the engine is at operating temperature) check to see if both the upper and lower radiator hoses are hot. If not, your thermostat may be stuck in the open position. It may be an intermittent issue because the thermostat may not always stick… just my first thought, of course assuming the radiator is full.
