Question about 2004 Mercedes-Benz C-Class

1 Answer

My a/c blows HOT on driver side & COLD on passenger side, and the temperature always read 50 degrees hotter than what it really is outside, like today it was only 75 degrees my screen indicated it was 103! Do you think there is a connection between the two & if so how can I fix the problem myself rather than taking it to a repair shop

Unfortunately the climate control system in your car is totally electronic. the outside temperature system is related to the other problems, most likely there is a problem with the climate control computer, but it could be many things in the system that has gone haywire, there is not any thing you can do to the system with out a scan tool, you might be able to go to autozone and see if they can retrieve the trouble codes from the climate control computer. but not all autozone's can get info from Mercedes-Benz they are kind of a breed of there own, good reliable cars but very difficult to work on and Mercedes very reluctant to give any info on their computer systems to anyone other then there certified dealers.and if you are not very careful with the electronics you can do even more damage they are very sensitive to static electricity.i would not recommend trying to repair the system yourself......sorry

My guess is that one of the hose's has a leak and needs to be replaced. A mechanic can run some tests to check if that's the case. Best of luck.

They are not vac on the h2. there is 2 for temp control, one for recirc and one for blend. check the hummer forum as there is a great read for it there. the driver side actuator is really ez as it's under the glovebox, 20 min fix. the rest take removing the whole dash but it's not that tough.

First thing that started the outside temperature reading would flicker and finally settled to the steady reading. Then we started getting cold air on the passenger side and warm air on the driver side. ...


That is two separate problems. The "Flickering" of the outside temperature thermometer might be normal to some extent. Sometimes, the voltage from the sensor is at a point where it could be say, 31 degrees F or 32 degrees F. The display may flicker back and forth between 31 and 32 very rapidly until the voltage changes just enough to go make it go solid one way or the other. It probably does this all the time, but you didn't notice until you were paying attention to the temperature problems inside the car. (One actually has absolutely nothing to do with the other.)

The cracking and popping noises you are hearing from the temperature door and the difference between the temperature on the driver's side and the passenger side are the same problem. Apparently, you have dual zone climate control. This is usually caused by one of the temperature doors sticking and either stripping the gears inside the door control actuator or breaking the door itself. If you have both sides set at "HOT", the side that is cold is your problem-child. This will usually also set a fault code in your climate control module and may make your climate control display flash. (but it doesn't always flash when there is a code present)

I have a 2005 ford freestyle the ac is fully charged the rear works great the front passenger side is ok but the drivers side is warm about 20 degrees difference between the drivers side an passenger


there is a door that directs cold or hot air behind the dashboard in order to make the passenger's side colder or hotter relative to the driver's side.
The a/c door servo may be bad, or the temperature settings for each zone are not balanced.

My inside temp led didplay always shows 50 degrees for my 2002 trailblazer so the Ac won't blow really cold air


If you mean the temperature display on the rearview mirror, you need to replace the outside temperature sensor. It is located under the hood, on the radiator support on the top near center.

2004 Chevy Silverado AC is blowing warm air on passenger side.


You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator
