ML270 heater fault

[zac]

Have been having a intermittent fault with the climate control/heaters not getting to full temp even when turned right up any suggestions?.

I had a similar problem. I found that if I turned it right down to cold for a few mins & then back up to max, it starts to work.

we did that and it worked again?, does this re-set it, and has yours done it again? mine seem to be ok know.

My ML270 had a moment the one time when it would only blow cold until I stopped, turned off the engine and restarted the engine, it again blew hot.

I asked the question on what the ML set up was, if it was an electric valve but did not get much info so unsure on what the system comprises of.

Thanks! it looks like when you turn the heater control down to cold it seen's to re-set the climate control, haven't had any problem since.
