Legacy bd5 , weak heat

Hi all,

I have a 97 legacy rs, I noticed the last day that the heater is working very poorly, there is some heat coming from the heater but it's very weak for 30 degrees. Any ideas what it could be?? The car is not overheating or anything and everything else is seem to work fine.

Thanks

Is there enough coolent in the engine and if so did you change coolent lately sometimes they can be a pain too bleed,I had too jack the front of mine.just simple things hope this helps!

Sometimes this is a sign that the thermostat is not working check that the head gasket is ok and oil is not mixing with coolant unscrew the oil cap check theres no gooey white deposits inside oil cap a tell tail sin there a problem. .
