Cold heaters

[chriswep91]

My heaters just blow out cold air.....Other then replacing the heater matrix what else is there that could be faulty?

Thanks

Jack the car up at the front and bleed the coolant system with the heaters on hot.

Failing that, whip the pipes off the heater matrix and stick a hose on the end and turn it on. That should flush it out.

I just cleaned a matrix out the other day you wouldn't believe the shit that comes out also if you read old posts taking the matrix out they say two bolts and slots out it's more of a fuck on than that

Thermostat stuck open?

Heaters been bled a few times and thermostat is new

If the matrix is flowing then theres zero reason it shouldnt blow warm air. Maybe check the air ducts are all operating.

The center 2 usually only blows cold unless you have the dial to face only by the way

I would also check the wire which goes from the back of the heater knob down to the back of the heater thing which the wire hooks onto unless this is just on gt's as had that problem before hope that makes sense.
