Re: My 1994 Mercedes E class 300 Diesel there is no heat
Check your fuses first.Does the temperature gauge read normal operating temperature (at least 80 degrees Celsius) if not replace your thermostat. Does the car have any heat while driving at higher RPM's? If so then you have a bad circulation pump. There is also a hot water valve (mono valve) that could be stuck in the closed position and not letting any hot water flow to the heater core.

I have a 2000 pontiac grand prix with a digital climate control system.
The heat quit working, it doesn't blow out any heat. Now that it is warm
outside the air stopped blowing out any air. The digital temperature on
the climate control is not correct. When it states that it is below 30
degrees on the ext and it is warm outside the air wont be cold. Once it
starts going above 30 degrees the air gets colder. Today the blower stop
working all together. Was told it maybe the climate control unit was
bad. You can hear the door opening/shutting when you switch the temp
from cold to hot. But there was no heat blowing out whatsoever in the
winter time. Could you please give me your opinion on whether or not it
is the climate control unit or something else?
start by inspecting your monovalve(located behind battery in engine compartment. The diaphragm is probably torn- you need to remove the 4 retaining screw off the lid and pull out the solenoid. on is the diaphragm. when it is torn hot water enters your heater core all the time
When you say 'biodiesel' do you mean true bio that is a mixed product or a combination of vege oil/diesel or pure vege oil? What is your daily air temp? Pure vege and even some combos with a high percentage of vege will thicken up in your injector pump, lines and injectors. If you're in a cold climate, I suggest moving the vehicle into a garage (preferrably heated) warm the car up as much as possible, using a tarp and heaters if nescessary. (Don't start a fire!) There also is a bolt on top of the water seperator (looks like a spin on oil filter in front of the engine) that you can loosen while you crank the engine until fuel comes out of the bolt hole. This removes any air trapped in the line. Hopefully you filled the H2O seperator with diesel prior to reinstalling it.Don't forget to add regular diesel to the fuel tank to thin out the vege, if that's where you put it. If you think that the mechanical fuel pump is giving up the ghost, I suggest trying an inline fuel pump from an early '90s Chevy diesel. It's electric and can be placed on the firewall near the inline filter, just bypass the mechanical and give it a battery source that is keyed.
Hello, This system has a few components that can cause this. You may have a bad temp regulator box, located behind the glove box, or a bad temp sensor, at center of the dash, or a bad pushbutton unit, (climate control panel} If you pull out your glove box, make sure that the foam hose that connects your temp sensor to the hard black tube is connected. This provides airflow across the sensor so it can work properly.
