    I have a 1992 190e that blows hot air out of the defroster vent (windscreen), even when the air conditioner should be blowing cold air (and probably no air from the defroster vents).

On the 1999 E class this is generally a problem when teh freon level is a little low. Sounds strange to blow cold on one side and not the other but recharging the system is the typical repair. You will also have to find the leak to keep this from happening in the future. There is an updated receiver drier for this vehicle depending on the vin number. The earlier version has a large(about the size of a nickle) sight glass in the top which cracks and allows freon to leak. The new version the sight glass is much smaller, about the sixe of a dime. Recharging the system should be the first step.

Damper mechanism for various vents is not working properly. If vacuum operated check all hoses and connections for possible vacuum leak. And do not overlook the switch that selects various dampers.

There is an issue with the air conditioner, the passenger side blows hot air and the driver side is cold. What do I need to do to fix this issue.


Hi,

Looks like your ventilation system is not functioning.
Under your dashboard is the ventilation housing, flaps that directs air from one point to another are stuck up or the one that controls it(mostly vacuums hoses and solenoid) is not working anymore.

The work to be done is to pull out the whole dashboard to gain access in that area.

I suggest you should bring that to your dealer or garage shop to fix that problem.

Hope that helps you!

Thanks for asking Fixya!

Air conditioner blows hot air


this can be a few different things going on. 1. does the clutch on your compressor engage when a/c is turned on? If so, does it cycle on and off constantely? If its cycling, your low on refridgerant, which indicates that theres a leak. System needs to be checked by professional. If compressor stays on, and you got hot air, it indicates that the problem is with the heater control valve. Normally, this can be found connected to one of the heater hoses located on passengerside engine compartment. It might be electronic, or vacuum operated.

start car.turn on air conditioner high cool .raise hood look to see if the compressor clutch is engaged and running.if yes your ac air door could be stuck closed or the air door vacuum actutator not receiving vacuum.a vacuum line is broken or off. or the control switch bad.that control the AC and heater mode. if compressor clutch is not engagged.check for power at compressor clutch.if yes compressor clutch coil open. or the air conditioner refrigerant R 134 is low take car to a private garage with a good reputation. they wont be expensive as the dealership.have them hook car air conditioner to a manifold gauge set to check your refrigerant low side and high side pressure.

E320 mercedes cold air only on passenger side.


More than likely you are low on freon. They will blow cold on the right then quit when low. If it is making a hissing noise charge system now. It is a process to get it going again with the computer climate control.

1999 Mercedes e-320 water pump


Good morning;
does this critter have a radiator fill w/cap? I've run accross som large Sotrd trucks that don't.
Well, anyway, it soesn't make sense you would need to fill the radiator via the resenoir. That is only good for short pressure relief and cook down vacuum recovery of coolant. 60/40 is the mix ratio. If it hs a resevoir it should have a radiator cap.The air in system will purge itself as it starts to circulatte cioolant. turn heater off till your system is full, then on when engine reaches operating temp. then if needed top iff coolant. Leave radiator cap off while waiting for coolant to start circulating. When thermostat opens out comes the air. Then put coolant mix in reservoir to fill line. check for leaks and all hose clamps are tight and you should be set, Good luck - Ned

Air conditioner problems


If the air blows from the derfost and the footwells, then their may be a vacuum leak. Check under the hood there should be a vacuum line that goes from the firewall to a vacuum port on the intake manifold. Alot of times the line get corroded and breaks off.(If you find the pcv hose you are in the right direction)
