For my 91 300e W124:

1) Previous owner took the strip fuse for the fan/blower out. When I put one in, the fan blows full blast on one speed, either off or on. No low, med, hi.

2) Light for the transmission dash is out. Cannot tell at night what gear you have.

3) Drivers side seat sometime goes crazy. Usually happens after I reconnect the battery, the seat will jump around, even though the seat adjustment button
is not touched.

4) Check engine light is on. The pulses indicate numbers 16 and 17.

16 - EGR switchover valve - should I just replace?

17 - I already changed the oxygen sensor about a year ago, as well as the OPV (fuse is good).


Are these issues all related? Where do I start?
