Hello, I am new to this board.
I thought I would post the problem I have with the ML320 that I am experiencing.
It has 80,000 miles on it.
One night recently when coming home the heater stopped working. Cold air comes through the vents.
Next day all the lights in the front panel stopped working and none of gauges are working.I disconnected the battery and connected it back with no improvement.
I checked the possible fuses and no response.
What do you think is the problem?.
I very much appreciate sharing your experiences of similar nature if you happened to have similar problems.
Thanks

 

is the engine temp normal? about 90-100 Celcius on your gauge? if its taking a long time for the engine to heat up could be the thermostat. if you car is heating up normally could be a bad headunit. make sure the cooling system has sufficient coolant. maybe there could be air in the coolant system. did you have any work done recently.

 

Chassis 221,
Thank you very much for your post with information.
The coolant level is good.
The engine heats up to the appropriate levels.
The hoses are nice and warm.There has not been any work done.
Thanks
