Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, it sounds like you may have two separate issues.
The heater control valve is a very common problem on the E class. I suspect that could be the cause of your lack of heat.
For your lack of cooling you may very well have a faulty compressor or a refrigerant leak in the system.
Nothing works - It was working one day and then everything stopped
Can that happen???
If everything occurred at once I suspect it would all be related then. Step one is to have the fault codes read in the climate control system with the Mercedes tester. The codes will point to the specific problems.
I need to take it to the dealership to get the codes read correct??
Everything did occur at once.
Yes, either a dealer or an independent Mercedes specialist.
As long as they have Star Diagnosis or the equivalent they can read the fault codes.
Thanks so much for your help. May I please print this conversation out of what I should have done?
