heating problem

[martin sea]

Hello and thanks for letting me in the group. I have a E class 250 CDI Sport its a beautiful car and a joy to drive. Recently I noticed that when the heating was turned up to high it remained lets say cold...? I have took it to the garage and they cannot find out what the matter is with the heating??? the temp guage remains at a steady 90 degrees on the dash board ... could anyone please tell me what the problem is to save me taking it to mercedes to charge me £120 for a diagnostic as I have already spent £250 with the mechanic who looked at it
thanks in anticipation

I've just had the same problem with my C220cdi.

Afraid to say that this will be costly to put right if using an MB dealer. I'd say that the heater blower/motor has failed.

You mostly likely looking at 2 days labour to pull out the dash and replace the heater blower.

See if you can get an Indy to diagnose and do the work as they will be cheaper than an MB dealer
