Guest petercabrio Posted November 29, 2015 I have been trying to get hot air from my heater with no success It goes from cold to warm when you turn the heat dial and I have checked behind the dash and its moving the arm all the way It's had a new matrix fitted All the hoses are hot in the engine bay The control dial moves air about There isn't any air in the system, it has new coolant with g12 The temp gauge only goes up to 90 before the fans cool it back down I am puzzled any help would be appreciated Quote Share this post Link to post Share on other sites
VW_chris 10 Posted December 1, 2015 did you recover the air directories inside of the airbox? they are covered in foam at the factory, which turns to dust over time, i pulled my dash out and just used duct tape to cover the plates up Quote Share this post Link to post Share on other sites
Guest petercabrio Posted December 1, 2015 I didn't replace the matrix, so did nt get to see inside The aux pump runs, if the impeller was broken or missing would that stop flow of water enough to cause warm heating Quote Share this post Link to post Share on other sites
Guest petercabrio Posted December 8, 2015 Right, now sick of this, it's annoying. The pump runs fine and then seems to run dry. Squeeze hose to reprime and works fine for two mins then runs dry The only thing I can think Is massive air lock or I need to swap hose to heater matrix back over, I changed these over when first bought the car Quote Share this post Link to post Share on other sites
