Gent's,

I recall seeing a thread related to the failure/replacement of the solenoid in the attached photo. I can't seem to locate the thread now, can someone assist with a link?

Thanks,
Nel

 

This is a repair thread.

 

Duovalve, no wonder my search was in vain. I appricate it 180!

 

It is in my list in my signature, under 'Heater and Air Conditioning' and titled 'Heater Valve Repair'.

Is this broken valve your problem? There is another repair in a MB forum where the valve leaks inside, I'll have to dig that one up again sometime. You have to drain the system so the level is below the valves or it will leak all over the place. Or maybe pinch of the hoses if possible.

 

pulled into a parking spot - all lights on dash came on and car stopped
came back 1 hour later and turned on ok but check engine lite is on

 

Get the CEL codes checked.
CEL = Check Engine Light.

 

Thanks for the tip, I'll be going through your signature to see what gremlins are waiting for me.


Don't know if its the broken valve or leaking valve yet, I hope neither but would settle for option 2.

I was looking for the the leaking valve thread but found these two.
