W126 560SEL, No heat.....
Hi,
My car doesn't blow any heat but cold air (warm air under the steering wheel) the heat worked great the day before. I did my research here and some said that i should replace the mono valve. I am wondering if anything i can do to test and make sure that the monovalve is going bad or not. And i am wondering what is the MPG on this car? someone from ebay ad said he can have a 23MPG.... and mine is only 14-18... a huge different! thanks and look forward to hearing from you guys! |

I discovered my mono valve was bad by driving the car with the heat on (which was only blowing cool air). I stopped the car for a few mins, started it again and hot air would blow for a minute or so, then it was back to cool. It seems the warm air from the engine was blown through...
14-18 mpg is about right. I get 12-15 city driving and probably around 20 mpg on the highway. |

I have a similar problem on my car. There's heat in city traffic and no heat on the freeway. If there's no heat at any time, it could also be a bad cabin temp sensor.
Aparently the monovalve is easy to repair/replace. It's under the ABS controller on your car. I'll know more when I fix mine hopefully this weekend. Sixto 91 300SE 81 300SD |

Thank you guy, guess i am going to get the monovalve first and see if it does the trick.
So the monovalve is located under the ABS controller? not somewhere near the battery? |

My 1987 560SEL has the same problem. Let me know if the monovalve replacement is the cure. Thank you

Also my 560SEL averages about 15-17 MPG.

The monovalve is between the battery and ABS controller. The ABS controller is that box or one of those boxes on the firewall just ahead of the wipers.
