Hi, new owner of a C180 1995. Very pleased with it but I have a problem which has just started.
My heating control dials flash, but when the car lights are switched on they go off and don't illuminate. The heating seams to be on hot all the time. This has only just happened today and I had no problems in the 2 weeks I've had the car. I can only find one similar topic but it did'nt really answer the issue.
Can you please advise. The car was serviced last week and the coolant was checked ?
thanks. Kev

Stripped down the duovalve but all parts were OK. Not dirty and reassembled. The flashing lights stopped for a short period and now intermitent, seems to flash when cold and stops when the engine is hot. Cann't understand whats happening perhaps its an electrical fault?#
Thanks for your help Busby. I'll live with it for while and see what happens.
thanks:confused:
