Hi I have a question related to this in a way. My 1997 e420 blower motor won't work. I already tried replacing it and resistor with the updated design. No luck. So I tested for voltage and had no voltage to the resistor at the smaller control wires but I do at the larger red wire. I then tested fuses 4, 7, and 8 at someone's recommendation elsewhere. No voltage to 7 or 8. Jiggling the key was suggested. No luck. Any thoughts?

Might have to replace the whole control climate control unit

[@slimsherman5818]

I cleared my codes but 1419 stayed on, does that mean the electromagnetic clutch is bad and needs replacing, got the e/c light to go off but no cold air, thanks

[@stefanyotcev5479]

mine ownt turn off aswell ... but does EC mean economic ? i tought it ment the air conditioning :D and can u tell me is the light is on it means its on or off ? ( the AC system )

Hi friend, I have a problem with my Mercedes Bens W210 E200 1998, the internal fan of the air conditioner never turns off, which I have to disconnect the battery every time I have to park it and it has me crazy, how can you help me or can you help me?

[@nathanmisicka6230]

Does the engine need to be running to get the 12v at yhe compressor?

[@benbrewer5853]

How do you turn the air on

[@OatesSteve]

Thank you for your video,, my ac has no Freon, shouldn’t my blower motor/ fan still blow & heater still work ? I have no heat or blower motor fan. Any help will be appreciated, Thanks Steve O

[@dieselmercedes7507]

heater needs to work even without freon in A/C system

[@DanielGutierrez-zu9fv]

@@dieselmercedes7507your blower resister from the blower motor is shor, the hot air is not being blown into the cabin.

How do I turn off my AC? I use a Mercedes c200

[@texan176]

How did you clear the codes from the system to make 12 volts go to the compressor on the wire in the car?

[@dieselmercedes7507]

That procedure is in other video you can find on my channel..Thanks.

Hey I know that voice! Toyota Maintenance channel ha ha My '05 Subaru Outback XT A/C Control Panel (Climate Control unit) is not turning on at all. I've checked the whole power and ground circuits, voltage, resistance, ground, connectors, etc. They all seem to be fine, still nothing, the Control Panel is not turning on. Any idea what this could be related to?

[@72nortoncommando]

have you ever had the need to remove the wood trim to access the ac control head and around radio?

[@dieselmercedes7507]

+Sal Cott not on this model….

How do I cut my air on

[@ginnyl7949]

how do you erase codes on climate control without a computer diagnostic tool

[@dendro1717]

You should speak up louder! You speak very soft, it's very difficult to hear you! Thank you!
