Hi every one again
Today I check air heater and its not work. I have 2 jaguars about 1 month only and don't try it before. On both cars air just little warm, I will use heater just in the morning time in the winter time (2 month in the florida). Today 93F (34 c) outside and air blow just little warm. It is should be cold outside to heater begin work? Or I have the problem?
Thanks

 

Is your temperture gauge showing an "N" reading, indicating the engine if fully warming up? If not the thermostat is probably stuck open....common problem. This will result in weak heater performance.

Next is check check the electric coolant pump that sned coolant to the heater core. They are known to fail. DO you hear/feel it running?

Cheers

Yes engine temp on the middle.
It have electric coolant pump? no, I don't check yet. So its should be hot? even if outside temp is high?
