Same problem here, not sure if same cause
Post Heater does not work when cold Still not fixed, my temp never got to 80, I replaced the thermostat. Now it does but still no go on the heat. I am told so far it is the "DUO" but I don't want to spend the $436 until I am sure it is it and not any other parts. I would think if your front defrost works but blows cold air all the time it may very well be a thermostat. Since I was told once that the front defrost should work in any case. Good Luck

Mercs are the only cars I've owned that tend to run cold when the thermostat fails. A 380SL and a 190E both suffered this way and a new 'stat fixed both. Cheapest first step possible.
Next, the fan. If I remember correctly, the 380 has an engine driven fan. These can fail by losing drive in the clutch, or locking up. If it locks up, it will over cool. |
