I have a 1994 Renault Clio, 1.2, which has been a very good car until last week. I was driving along at 30 mph when the temperature warning light came on, and the heater ceased to function. The thermostat has since been replaced but no improvement.. Can you suggest what is wrong?

The heaters will not blow hot if there is no coolant in them.Since it has been worked on, There might be some air trapped in the heater core

Suggested Repair

Check that the heater core has coolant and bleed any air trapped in the heater core after the thermostat work.

A 1994 Renault Clio 1.2 showed a temperature warning light and lost heater function while driving. Replacing the thermostat did not help. The expert said the heater will not blow hot without coolant and that air may be trapped in the heater core after the recent work.
