Larry, when you say controller you mean the push button module, right? BTW, thanks for the troubleshooting tip - I will defintely try this and unplug the monovalve assembly over the weekend.

My tech is betting it's the monovalve, with the ACC module a close second. I have a spare ACC module so will test this first before purchasing a monovalve. I did notice that the faster I drove and the longer I was on the road, the colder it felt, but that may have been a cumulative effect... The classic symptom of a torn monovalve insert is heat ONLY at low engine RPM. It is possible, but not likely, that a damaged insert would cause no heat. But it could be electrical failure. I'd unplug the electrical connector on the monovalve and go for a drive. That is the full heat setting. If there is still no heat, it has to be the monovalve or the coolant flow. If there is heat - then it's the controller. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

Re: [MBZ] 1985 300TD Blows Ice Cold no matter how cold it is outside - even with the heat on!
Larry, when you say controller you mean the push button module, right? On that system, the actual controller is separate from the pushbutton module. Every PBU I've had has had problems, but I've never had a controller go bad. The PBU just selects functions, and gates the signals for the mode you are in. The later systems, without the translucent Auto speed button bar, are entirely integrated into the PBU. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

I would start with looking at the monovalve. As for the disparity in prices, I would suspect that the URO folks are somehow involved. A URO rep surfaced a while ago over at BenzWorld and he tried to defend their products. Needless to say he went quiet rather quickly as people took him to task over URO's crappy parts.

Re: [MBZ] 1985 300TD Blows Ice Cold no matter how cold it is outside - even with the heat on!
That system has two primary ills: bad solder joints in the pushbutton array, and a split monovalve insert. The former makes it insane, and unable to do what it should, and the latter just plain prevents heat. The tertiary ill is a rotted foam hose going to the cabin air temperature sensor, which makes it unresponsive to in-cabin air temperature. All are easy fixes, for the handy. (Assuming, now, that you can _get_ a decent monovalve insert.) -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

Yeah, GMail in conversation mode aggregates all responses, although some are private. I still am getting used to this. Also, your questions was in tiny type that I could barely read.

Re: [MBZ] 1985 300TD Blows Ice Cold no matter how cold it is outside - even with the heat on!
Hi Andrew, Go with a new OE mono-valve. I had the same issue and bought 2 chinese mono-valves from Rusty before crying uncle. The OE ($146 IIRC) has worked perfectly since it was installed almost 3 winters ago. The cheap Chinese ones would get a little tear in the rubber diaphragm allowing the coolant (under pressure) to get where it shouldn’t. The other 2 issues that will affect you are the actual sensor itself (under the little grill in your dash) and the tube. I do not think that these are your problem now, but if you replace them…..your system will work completely as designed. I did both, and my wife has no more complaints about the temperature control.

The classic symptom of a torn monovalve insert is heat ONLY at low engine RPM. It is possible, but not likely, that a damaged insert would cause no heat. But it could be electrical failure. I'd unplug the electrical connector on the monovalve and go for a drive. That is the full heat setting. If there is still no heat, it has to be the monovalve or the coolant flow. If there is heat - then it's the controller. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.

Pull the electrical connector at the monovalve. That should let the monovalve stay full open. If still no heat, the monoalve insert is toast.
