Mercedes is a good company and the answer to you're queston is NO.
To replace the heater core in a 1993 Mercedes-Benz 190E, first disconnect the battery and drain the coolant. Then, remove the dashboard and any components obstructing access to the heater core, including the center console and HVAC controls. Disconnect the hoses from the heater core, remove the mounting screws, and carefully extract the old heater core. Install the new heater core by reversing the process, ensuring all connections are secure before reassembling the dashboard and refilling the coolant.
To bypass the heater core on a 1991 Mercedes 190E, you need to locate the heater hoses connected to the core in the engine bay. Disconnect the hoses from the heater core inlet and outlet, typically found on the firewall. Then, use a short piece of hose or a bypass fitting to connect the two hoses together, effectively rerouting the coolant flow and bypassing the heater core. Ensure all connections are secure to prevent leaks.
If the heater in your 1993 Mercedes 190E is not working, first check the coolant level, as low coolant can prevent proper heating. Next, inspect the thermostat and heater core for any blockages or leaks. Additionally, examine the heater control valve and the dashboard controls to ensure they are functioning correctly. If these components are in good condition, it may be necessary to consult a professional mechanic for a more in-depth diagnosis.
Disconnect the send and return lines from the heater core and use a hose coupling and hose clamps to connect these two lines together
it is probably the heater control valve see my tutorial on this at http://www.benzworld.org/forums/w201-190e-d-class/1358590-troubleshooting-mercedes-benz-190-e-d-210-tempmatic-climate-control-system.html#post2716281
The heater fan on a 1985 Mercedes 190E is typically located under the dashboard on the passenger side of the vehicle. To access it, you may need to remove the passenger-side footwell panel. The fan is part of the heating and ventilation system, which also connects to the climate control unit. Make sure to disconnect the battery before performing any maintenance to avoid electrical issues.
How do you remove a radio from a 190E?
There are two possibilities. Its either on the overhead console by the rear view mirror or on the center dash control switches below the heater vents.
It sounds like you have no coolant flow through the heater core or the core is plugged
Sounds like low coolant or air in the cooling system
If you look on the backside of the climate control unit in the dash you will find a glass buss style fuse. It will be blown. Replace the fuse and your fan will stay on with your headlights.
A Mercedes 190e doesn't have a carburetor. They are fuel injected.
