On my '92 300SE the instrument warning lights will all come on at once and flash once or twice usually by using the directional signal. With the engine running and the car stationary I can make it do this by turning the hazard switch on/off. Just had all the plugins on the cluster reseated while the evaporator was changed...no help. Anyone seen this....is the cluster circuit board defective?
This S(ad) class car should've been recalled!! The door closing assist pump is now out to be rebuilt...what's next?
Thanx for any ideas.
