Question
I have replaced the pulse sensor in the differental, I have also replaced the instrument cluster to no avail, the speedometer is still not working.Please advise.
My blower switch only works on high also. I have replaced the switch, but it still only works on the highest setting.

Answer
Not knowing what model you have makes it kind of hard to diagnose.But BMW's use an electerical speedo.You were in the right place but have you check the wiring from rear to the front?Get your OHM meter out and start measuring...sounds like a broken wire...as for the blower check the grounds in that circuit.
