I have a renault clio 1.2 1994/1995. A year ago the heater stopped giving any heat, still blowing out fine but no heat apart from minimal on the lowest blowing setting. I had a new heating matrix fitted and had heat for a couple of days and then it stopped. I had it all investigated last week and he put some solvent through the system to flush it out but this didn't work. He now says i need a new heater matrix...i wouldn't mind but it didn't work last time what's to say it will work this time?! Anyone got any advice or tricks to fix this without another new matrix? Or could tell me why it is doing this?!
Any help much appreciated.
