chriswep91 Posted September 15, 2017 Share Posted September 15, 2017 My heaters just blow out cold air.....Other then replacing the heater matrix what else is there that could be faulty? Thanks Quote Link to post Share on other sites
morgey Posted September 15, 2017 Share Posted September 15, 2017 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. Quote Link to post Share on other sites
Gainzy Posted September 15, 2017 Share Posted September 15, 2017 (edited) 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 Edited September 16, 2017 by Gainzy Quote Link to post Share on other sites

chriswep91 Posted September 16, 2017 Author Share Posted September 16, 2017 Heaters been bled a few times and thermostat is new Quote Link to post Share on other sites
morgey Posted September 16, 2017 Share Posted September 16, 2017 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 Quote Link to post Share on other sites
patman Posted September 16, 2017 Share Posted September 16, 2017 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.
