Hi ya. Did you ever solve this. I've got same problem mine!Hi guys! Newbie here! Just bought a 2008 308. Problem is the heater not hot. Now, thermostat been changed, matrix flushed.
It does go cold when turned to position, just hot ain't hot! I'm suspecting electrical. Any ideas?
am going to try this for mine,where is the bleeder cap though, i've seen pictures of several..is there one by the bulkhead near the heater pipes ? thanks. ps 2010 308 1.6.Have you flushed and replaced coolant recently?
First get the engine warm but not hot! Carefully remove the expansion cap, then remove the bleeder cap,(try not to drop it) replace bleeder cap when all air has passed and coolant starts flowing out, check level and replace expansion cap!
Take the car for a short spin try the heating again then repeat until no air is in the system - if that fails, then get it scanned!
Mines pretty much the same, on low blower the heat is hot..although not as hot as it has been..when the blower is turned up the air is colder, certainly not what I would call warm even. I took out and cleaned the pollen filter, which was new in April, and gave it a good clean out but it hasn't affected the heat but will affect the volume of air the blower pushes through.. I also topped up the header tank which was only on low, now it's just below the high mark. Am going to test it again today and check at what temp the thermostat is opening..when it's stopped raining.I'm sure thermostat is good. Up to 90 degree in about 3 miles and then stays there all journey. Metal Heater pipes entering heater are too hot to touch. On low fan speed heater is warm but on 3 or above barely Luke warm.my wife's 206cc hot after 1 mile.
