Hello everyone, i am new to this forum and i bought my first MB 10 days ago. its a 2005 C230 AMG PKG. i think i got it for a perfect price. the car has 75,000 KM on it and i paid 8,000$ for it. The first time i checked the car everything was working perfectly, when i went to pick it up there was no heat, the heater blows cold air, i already checked the forum and tried almost everything and went to two certified Benz mechanics and i still didnt have my problem solved. things i did. 1-flush 2-replace the auxiliary water pump ( beside coolant ) 3-change the blower motor. over 700$ in parts and its not working yet. i dont know what might the problem be , i really like the car its in BRAND NEW condition. i really need your help guys any advise or suggestion would really help me.
