hi guys, having some issues with the heater in my vr. when vehicle is moving the fan will blow nice hot air. when the vehicle is stoped the heat drops right down, not cold but noticeably cooler. have replaced heater tap, and the control flap on the heater box is fine and working like it should. the pipes going to the heater core are nice and hot. has anyone got any ideas as to the cause of this issue? cheers ash
How does it go when you have it on recirc?
"If anyone disagrees with anything I say, I am quite prepared not only to retract it, but also to deny under oath that I ever said it." --T. Lehrer
"The secret of success is sincerity. Once you can fake that you've got it made." -- Jean Giraudoux
When you say the heat drops right down, do you mean that the volume of hot air decreases (ie. fan speed drops), or that the volume stays the same but the temperature goes down?
Have you replaced the thermostat to ensure the engine is at the correct temp?
May be a blocked heater core or the water pump isn't shifting enough volume of water at low engine speed.
If I told you I was a compulsive liar, would you believe me?
